Question

A store owner buys a total of 4,000 items for two different products. for shipping costs, it is $0.10 per item of product a and $0.04 per item of productb. if the total shipping cost is $352, which system of equations can be used to determine how much of product a and product b the store owner bought?

Answer 1

It's C

x+y=4000

0.1x+0.04y=352

trust me

Answer 2

I beleive the system of equations would be:

a+b=4000

0.1a+0.04b=352

I cant say for sure because the question did not list the cost of a and b together but rather the number of both items together
