[Question]Ali, Nada, and John have a total of $67 in their wallets. Ali has $5 less than Nada and John has 4 times more than Nada. How much money does John have?
[Answer]Let's say that N is what Nada has, J is what John has, and A is what Ali has. We know that A = N - 5 and J = 4N. We also know that: N + A + J = $67. We can substitute the equations from step 1 into the equations from step 2 to get: N + 4N + (N - 5) = $67. Combining like terms gets us 6N - 5 = $67. So, N = ($67 + 5) / 6 = $12. Substituting $12 back into the equation J = 4 N, we find John has 4 x 12 = $48. The answer is 48.

[Question]Sydney and Conner are having a three day rock collecting contest to see who can have the largest collection after adding to their existing collections. Before they start, Sydney has 837 rocks and Conner has 723. On day one, Sydney collects 4 rocks and Conner collects 8 times as many. On day two Sydney rests and Conner collects 123. On the third day, Sydney collects twice as many as Conner did on the first day. How many does Conner have to collect on day three to make sure he at least ties Sydney?
[Answer]On day one Conner collects 32 rocks because 8 x 4 = 32. On day three Sydney collects 64 because 32 x 2 = 64. After three days Sydney has 915 rocks because 837 + 0 + 4 + 64 = 905. Before the third day Conner has 878 because 723 + 32 + 123 = 878. Conner needs to collect 37 on day three to tie Sydney because 905 - 878 = 27. The answer is 27.
Q: Jacque arrived in France and his suitcase weighed 5 pounds. While in France, he picked up 5 bottles of perfume that weighed 1.2 ounces each, 4 pounds of chocolate, 2 bars of soap that weighed 5 ounces each and 2 jars of jam that weighed 8 ounces each. Considering 16 ounces is the same as 1 pound, how much did Jacque's suitcase weigh on the return flight home?
A: He bought 5 bottles of perfume that weighed 1.2 oz each so they weighed 5 * 1.2 = 6 oz. 2 bars of soap weighed 5 oz each so they weighed 2 * 5 = 10 oz. 2 jars of jam weighed 8 oz each so they weighed 2 * 8 = 16 oz. The perfume is 6 oz, the soap is 10 oz and the jam is 16 oz for a total of 6 + 10 + 16 = 32 oz. 16 oz is 1 pound, and he had 32 oz in products so he had 32 / 16 = 2 pounds of products. His suitcase weighed 5 pounds, and the chocolate weighed 4 pounds and the remaining products weighed 2 pounds so his suitcase weighed 5 + 4 + 2 = 11 pounds. The answer is 11.
Question: Ravi has some coins. He has 2 more quarters than nickels and 4 more dimes than quarters. If he has 6 nickels, how much money does he have?
Answer:
Ravi has 6 + 2 = 8 quarters. He has also 8 + 4 = 12 dimes. A nickel is worth 5 cents so Ravi's nickels amount to 6 x 5 = 30 cents. A quarter is worth 25 cents so his quarters amount to 8 x 25 = 200 cents. A dime is worth 10 cents so his dimes amount to 12 x 10 = 120 cents. therefore, Ravi has 30 + 200 + 120 = 350 cents. The answer is 350.
