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

According to correction

;

Option 1st

yes,it is correct.
  • 1.08(x+9.01+0.98+5.01)=21.87

The only way to verify is to solve ourselves

  • 1.08(x+15)=21.87
  • (x+15)=20.25
  • x=5.25

Yes she is correct
