Question

Which equation represents the following situation? Matt spent $13 on two magazines and some erasers. If the magazine costs $3.50 and each eraser costs $1.50, how many erasers did he buy, and what is the answer?

A. 2m + 1.5e = 13
B. 3.5m + 1.5e = 13
C. 1.5m + 3.5e = 13
D. 1.5m + 2e = 13

Answer 1

The equation that represents the given situation is A. 2m + 1.5e = 13. To solve this equation, we can set up a system of equations to represent the cost of the magazines and erasers. The cost of the magazines is $3.50 per magazine, and the cost of each eraser is $1.50.

Step-by-step explanation:

The equation that represents the given situation is A. 2m + 1.5e = 13.

To solve this equation, we can set up a system of equations to represent the cost of the magazines and erasers. Let's use m to represent the number of magazines and e to represent the number of erasers. The cost of the magazines is $3.50 per magazine, so the cost of m magazines is 3.50m. The cost of each eraser is $1.50, so the cost of e erasers is 1.50e. We can set up the equation as follows: 3.50m + 1.50e = $13.

Therefore, the equation that represents the situation is A. 2m + 1.5e = 13.
