Final answer:
By dividing the total earnings of $1380 from last week by the price per scoop of $72, it is calculated that Mr. Morgan's ice cream shop will sell about 19 scoops. Rounding down to the nearest whole scoop gives us 18 scoops.
Step-by-step explanation:
The student is asking how many scoops Mr. Morgan's ice cream shop will sell if it made $1380 last week and sells each scoop for $72. To determine this, we need to divide the total earnings by the price per scoop. Therefore, we divide $1380 by $72 per scoop.
$1380 ÷ $72 per scoop = 19.17 scoops
Since you can't sell a fraction of a scoop, we'll round down, because you can only sell whole scoops. Mr. Morgan will sell about 19 scoops. Looking at the answer choices provided, the closest whole number of scoops he can sell is 18 scoops, which is choice b.
