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 + 0.85 x = 5.27. 0.85 x = 8.67. x = 10.2 pounds. Where, if anywhere, did Carina make an error?
9f-11-(14f+4)=0 9f-14f-4-11=0 add all the numbers together, and all the variables -5f-15=0 We move all terms containing f to the left, all other terms to the right -5f=15 f=15/-5 f=-3
