Answer:
Option C, Carina should have subtracted 3.40 from 5.27.
Step-by-step explanation:
<u>Step 1: Convert words into an equation</u>
Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound.
3.40 + 0.85p = 5.27
<u>Step 2: Solve for p</u>
3.40 + 0.85p <em><u>- 3.40</u></em> = 5.27<u><em> - 3.40</em></u>
0.85p / 0.85 = 1.87 / 0.85
p = 2.2
The error was found when she add 3.40 to 5.27 instead of subtracting.
Answer: Option C, Carina should have subtracted 3.40 from 5.27.
