Answer the following question.
The ratio of boys to girls at the dance was 3:4. There were 60 girls at the dance. The teachers were 20% of the number of boys. How many people were at the dance?
Step-by-step reasoning process: 60 girls represent 4 parts, so one part of students is 60 / 4 = 15 students. There are 15 * 3 = 45 boys at the dance. The teachers at the dance are 45 * 0,2 = 9 teachers at the dance. There are 60 + 45 + 9 = 114 people at the dance.
The answer is 114.

Answer the following question.
A small pizza has 6 slices, a medium pizza has 8 slices whereas a large pizza has 12 slices. How many slices of pizza will you have if you bought a total of 15 pizzas and you know you ordered 4 small pizzas and 5 medium pizzas?
Step-by-step reasoning process: We know that 4 small pizzas and 5 medium pizzas = 4 + 5 = 9 non - large pizzas were purchased. Because a total of 15 pizzas were purchased then 15 - 9 = 6 large pizzas were ordered. If 1 small pizza has 6 slices then 4 small pizzas will have 4 * 6 = 24 slices. Similarly, If 1 medium pizza has 8 slices then 5 medium pizzas will have 5 * 8 = 40 slices. Similarly, If 1 large pizza has 12 slices then 6 large pizzas will have 6 * 12 = 72 slices. That means in total we have 24 small slices + 40 medium slices + 72 large slices = 24 + 40 + 72 = 136 slices of pizza.
The answer is 136.

Answer the following question.
Zach is saving his money to buy a brand new bike that costs $100. His weekly allowance is $5. His parent will pay him an extra $10 to mow the lawn. His neighbor will pay him $7 per hour to babysit their son. He has already saved up $65. He'll receive his allowance on Friday and he's planning on babysitting for 2 hours this Saturday after he mows the lawn. How much more money does Zach need to earn before he can buy the bike?
Step-by-step reasoning process: If he babysits for 2 hours at $7 per hour, he will earn 2 * 7 = $14. This week he will earn $5 allowance, $10 mowing the lawn and $14 from babysitting for a total of 5 + 10 + 14 = $29. If we add the $29 he will earn to his $65 savings, he will have a total of 29 + 65 = $94. The bike costs $100 and he will have $94 leaving $100 - $94 = $6 more that he will need to earn.
The answer is 6.
