Brian works at an ice cream shop. For every
4 scoops of chocolate ice cream
sold, 5 scoops of vanilla are sold and 2
scoops of strawberry are sold.
Draw a picture to represent how many
chocolate, strawberry, and vanilla
scoops are sold when eight scoops of
chocolate are sold.
Express the ratio of vanilla scoops to
strawberry scoops as a decimal when 12
vanilla scoops are sold?
Does the ratio expressed as a decimal
change when 8 scoops of strawberry
are sold?
Why or why not?

answer:

3 bags of apples and 2 bags of oranges.

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
