Answer:
Step-by-step explanation:
The total tip left by the boys amounted to 15% of the pre-tip bill. Let p represent the pre-tip bill.
Then 0.15p = $10.50 (p is the pre-tip bill and 0.15 represents 15% of that)
Dividing both sides by 0.15 results in an expression for p:
p = $10.50 / 0.15 = $70.
Recall that p is the sum of the costs of the individual meals. If this total was $70 and Michael's dinner cost $40, Elijah's dinner must have cost
$70 - $40, or $30.
