Question

The soccer team is planning to sell health bars for a fundraiser. The prices of purchasing health bars from two different companies are represented by the system of equations shown, where x is the number of bars purchased and y is the total cost in dollars.

Company A: y = 0.75x
Company B: y = 10 + 0.50x

How many bars would the team need to purchase from each company in order for the total cost to be equal?

Answer 2

So in order to be equal both y and x must be equal to each other, this means we will be using substitution to solve this problem.

Answer 3

.75x=10+.50x
.25x=10
x=40

Answer 4

Now plug in x to solve for y.
