Question: Gina is figuring out how much she'll have to spend on college this year. She's taking 14 credits that cost $450 each, and she has to pay $120 for each of her 5 textbooks plus a $200 facilities fee. How much will Gina spend in total?
Answer: First, find out how much will Gina pay for tuition by multiplying her number of credits by the cost per credit: 14 * 450 = $6300. Then find out how much she pays for textbooks by multiplying the number of books by the cost per book: 5 * 120 = $600. Finally, add up all Gina's costs to find the total of 6300 + 600 + 200 = $7100. The answer is 7100.
[Question]Two stores sell the same model of smartphone, but they offer it at different prices and with different discounts. Store A lists the smartphone at a full price of $125 and offers an additional discount of 8%. Store B lists the same smartphone for $130 and offers an additional discount of 10%. After both stores' discounts are applied, how much cheaper is store A's smartphone than store B's smartphone?
[Answer]Store A has a $125 x 8 / 100 = $10 discount. So the smartphone from store A will only cost $125 - $10 = $115. Store B has a $130 x 10 / 100 = $13 discount. So the smartphone from store B will only cost $130 - $13 = $117. Thus, store A's smartphone is $117 - $115 = $2 cheaper than that of store B. The answer is 2.
Q: Mary and Ann are going sledding. Mary slides down a hill that's 630 feet long at a speed of 90 feet/minute. Ann slides down a hill that's 800 feet long at a rate of 40 feet/minute. How much longer does Ann's trip take than Mary?
A: First find the total time Mary's trip takes: 630 feet / 90 feet / minute = 7 minutes. Then find the total time Ann's trip takes: 800 feet / 40 feet / minute = 20 minutes. Then subtract Mary's time from Ann's time to find the difference: 20 minutes - 7 minutes = 13 minutes. The answer is 13.
Question: There were 10 snowflakes at first. It snowed an additional 4 snowflakes every 5 minutes. How many minutes passed before there were 58 snowflakes?
Answer: Without the first 10 snowflakes, there are 58 - 10 = 48 snowflakes needed. 48 / 4 = 12 5 - minute intervals are needed to get the additional snowflakes. 12 * 5 = 60 minutes passed. The answer is 60.
[Question]The sum of the ages of two friends, Alma and Melina, is twice the total number of points Alma scored in a test. If Melina is three times as old as Alma, and she is 60, calculate Alma's score in the test?
[Answer]If Melina is three times as old as Alma, and she is 60, Alma is 60 / 3 = 20 years old. The sum of their ages is 60 + 20 = 80 years. Since the sum of Alma and Melina's age is twice the total number of points Alma scored in a test, Alma's score in the test was 80 / 2 = 40 points. The answer is 40.
[Question]It is Roger's turn to provide a snack for the baseball team after the game and he has decided to bring trail mix. The trail mix comes in packs of 6 individual pouches. Roger has 13 members on his baseball team, plus 3 coaches and 2 helpers. How many packs of trail mix does he need to buy?
