x = 10.2 pounds.

Where, if anywhere, did Carina make an error?
Carina did not make any errors.
The initial equation that Carina wrote was incorrect.

Answer 2

Answer:

Carina did error

Step-by-step explanation:  

Given data  

Carina spent a total of $ 5.27

she bought pineapple for $ 3.40

tomatoes which are on sale for $ 0.85 per pound

to determine the number of pounds Carina wrote x as number of tomatoes and solved as below

                          ⇒  3.40 + 0.85$x$ = 5.27   [take as equ (1)]

                          ⇒ 0.85 $x$ = 8.67              [take as equ (2)]

                          ⇒ x = 10.2                      [take as equ (3)]

here we need to find whether Carina did any error or not ?

⇒ Here Carina is wrong

⇒ In equ (2) she added 3.40 to 5.27 that was the mistake

⇒ here she need to subtract 3.40 from 5.27

⇒ the following is the correct process

           ⇒   3.40 + 0.85x =5.27

           ⇒   0.85x = 1.87

           ⇒ x = $\frac{1.87}{0.85}$ = 2.2

therefore correct answer is 2.2 pounds
