Answer:
9 cups of lemonade
Step-by-step explanation:
First, calculate the amount of money Pablo earns every week:
$5 + $7 + $18 = $30
Calculate how much money Pablo gets each week by selling lemonade:
$30 - $12 = £18
Calculate how many cups of lemonade are being sold each week:
18 ÷ 2 = 9
Pablo needs to sell 9 cups of lemonade each week to reach his goal
