“the 7th grade class is planning a pancake breakfast. all materials are donated except the pancake mix. based on the given information below, answer the questions that follow:
- bags of mix cost $10 each
- each bag makes 120 pancakes
- each person will be served 3 pancakes
a.) how many pancakes would the students need to make to serve 240 people?
b.) how much will it cost for all of the bags of mix needed to serve these 240 people?

a) 720

b) 60$

Step-by-step explanation:

a) each person is served 3 pancakes and there are 240 people, 240 x 3 = 720.

b) Each bag of mix costs 10$ and can make 120 pancakes, but we need 720 pancakes, which means six bags of mix (since 120x6 = 720). Since each cost 10$, 10 x 6 = 60$

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
