Robbie is going shopping he has more than $65 to spend he wants to buy a pair of shoes for $21.95 and some shirts that cost $10.50 each which inequality can Robbie use to determine how many shirts s he can buy A. 10.5 S +21.95 >65 B. 10.5 S +21.95< 65 C. 10.5 S +21.95->65 D. 10.5 S +21.95 -< 65

Explanation:

The 10.5s represents the cost of buying all the shirts only. Each shirt costs $10.50 so buying s of them (s is some positive whole number) costs 10.50s which is the same as 10.5s

Then we tack on the price of the shoes to get to be the total amount Robbie spends, which is in dollars. This amount must be 65 or smaller which leads to the final answer shown above.
