Jackie is a toll booth employee. One day, she wrote the expression:0.75m = 15.75She let m represent the number of motorcycles that crossed the bridge that day

21

Step-by-step explanation:

The expression Jackie came up with is:

0.75m = 15.75.

To get the value of m, we divide both sides by 0.75

0.75m = 15.75.

0.75m/0.75 = 15.75/0.75

m = 1575/75

= 21
