Question

Jennifer bought 8 shirts for a total of $55. Red T-shirts cost $10, and white T-shirts cost $5. Which system would be used to solve the problem?

a) System A: 10x + 5y = 55, x + y = 8
b) System B: 10x + 5y = 8, x + y = 55
c) System C: 5x + 10y = 8, x + y = 55
d) System D: 5x + 10y = 55, x + y = 8

Answer 1

To solve the problem of Jennifer's shirt purchase, we can use the system of equations A: 10x + 5y = 55, x + y = 8.

Step-by-step explanation:

In this problem, we need to find the system of equations that represents Jennifer's purchase of 8 shirts for a total of $55, with red T-shirts costing $10 and white T-shirts costing $5.

We can set up the system of equations using x and y as the number of red and white T-shirts, respectively. Since Jennifer bought a total of 8 shirts, the first equation is x + y = 8. And since the total cost of the shirts was $55, the second equation is 10x + 5y = 55.

The correct system of equations to solve the problem is a) System A: 10x + 5y = 55, x + y = 8.
