Question

Write an equation to help you find the value of each variable. Solve the equation.

a) 60% of C is 43.2 b) 38% of E is 190

Answer 1

C=72

E=500

Explanation:

Is means equals and of means multiply

a) 60% of C is 43.2

.60 *c = 43.2

Divide each side by .60

c = 43.2 / .6

C =72

b) 38% of E is 190

.38 *E = 190

Divide each side by .38

E = 190/.38

E =500

Answer 2

C = 72

E = 500

Explanation:

Is means equals and of means multiply

a) 60% of C is 43.2

.60 *c = 43.2

Divide each side by .60

c = 43.2 / .6

C =72

b) 38% of E is 190

.38 *E = 190

Divide each side by .38

E = 190/.38

E =500
