Answer:
$18.75
Step-by-step explanation:
This is kind of a trick question. Instead of giving you 1 example they give you two.
Basically, this question is trying to test your reading skills.
31.25 is being charged for 5 hours. So, how much is being charged in 1 hour?
well, dividing 31.25 by 5 brings us to the result of 6.25. Meaning 1 hour of babysitting costs $6.25
Now that we know the cost of 1 hour, we need to multiply this by 3.
6.25 x 3 = $18.75
we can also 'test' our answer to make sure it is correct by multiplying 6.25 by 8. (doing so is confirming 8 hours of work is $50 at $6.25 per hour)
hope this helpd!
