Question

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. To

determine the number of pounds of tomatoes that she bought, x, Carina wrote and solved the equation as shown below.
3.40+0.85x -5.27
0.85X-8 67
X = 10.2 pounds
Where, if anywhere, did Carina make an error?
A. Carina did not make any errors.
B.The initial equation that Carina wrote was incorrect.
C.Carina should have subtracted 3.40 from 5.27.
D.Carina should have divided 8.67 by 0.85.

Answer 1

The correct answer is option C, Carina should have subtracted 3.40 from 5.27.

Step-by-step explanation:

Carina made an error in her calculation. The correct equation should have been 3.40 + 0.85x = 5.27, instead of 3.40 + 0.85x - 5.27.

To find the number of pounds of tomatoes that she bought, Carina should have solved the equation 0.85x = 5.27 - 3.40, which simplifies to 0.85x = 1.87.

To determine x, she should have divided both sides of the equation by 0.85, giving x = 1.87 / 0.85 = 2.2 pounds of tomatoes. Therefore, the correct answer is option C, Carina should have subtracted 3.40 from 5.27.
