Hillary works at a video store. she earns $8.50 per hour plus 12% commission on all the weekly sales she makes. If she works 24 hours in a week, which expression best describes her sales (x) if she earns at least $324 during that week

Answer :

Answer: See explanation

Step-by-step explanation:

Let her sales be represented by x.

Based on the information given in the question, the equation to calculate her sales goes thus:

(8.50 × 24) + (12% × x) ≥ 324

204 + (0.12 × x) ≥ 324

204 + 0.12x ≥ 324

0.12x ≥ 324 - 204

0.12x ≥ 120

x ≥ 120/0.12

x ≥ 1000

Her sales is at least $1000
