Answer: $26
Step-by-step explanation:
Let the number of $2 price increases be x.
This means that if the price is 10+2x, 42-2x shoes are sold.

Answer:
-6 ≥ r
Step-by-step explanation:
–5 ≥ 5 (r+5)
Divide each side by 5
–5/5 ≥ 5/5 (r+5)
–1 ≥ (r+5)
Subtract 5 from each side
-1-5 ≥ r+5-5
-6 ≥ r
It’s 17 bc you always do the parentheses first the so left to right
