Question

Yes, it is correct

No, because in step 5 the 5.25 should be 6.12

No, because in step 4 the 5.67 should be 1.62.

No, because in step 2 only the x should be multiplied by 1.08.

Answer 1

Answer:In Heather's solution to the problem, she wrote and solved an equation.

Her work is:

Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87

Solving like terms

1.08(x+15}=21.87

dividing both side by 1.08

we get

x+15=21.87/1.08

x+15=20.25

subtracting both side by 13.9198

x=20.25-15

x=5.25
