Answer: 7 (10) + 8 x ≥206
Explanation:
Hi, to answer this question we have to write an inequality with the information given:
So, she worked 7 hours at a dinner for $10 per hour (7 x 10 = 70)
She also makes $8 per hour when she babysits (8 x, where x is the number of hours she babysits)
The sum of both earnings must at least 206 (more or equal) if she wants to buy the prom dress.
Mathematically speaking
7 (10) + 8 x ≥206
Simplifying
70 +8x ≥206
