Gavin went on 24 runs last month that totaled 100 miles. Each run was a distance of either 3 miles or 5 miles. Which system of equations can be used to determine the number of 3-mile runs, x, and the number of 5-mile runs, y, that Gavin went on last month?
A. x + y = 100
3x + 5y = 24

B. x + y = 100
5x + 3y = 24

C. x + y = 24
5x + 3y = 100

D. x + y = 24
3x + 5y = 100

i believe we dd this one yesterday

jojo4eva · Answer

x+y are equal to 24 to show how many miles her ran. He went on 24 runs and the information says that 3 goes with x and 5 with y thus u have 3x+5y=100
