My question is: When Erick went to the market to sell his fruits, he realized that the price of lemons had risen by $4 for each lemon. The price of grapes had also increased by half the price that the price of lemon increased by per grape. If he had planned to sell the lemons at $8 and the grapes at $7, and he had 80 lemons and 140 grapes in his basket, how much money did he collect from selling the fruits at the new prices? Your thoughts:
The new price for each lemon after increasing by $4 is $8 + $4 = $12. For the 80 lemons, Erick received $12 * 80 = $960. The price of each grape increased by 1 / 2 * $4 = $2. The new price at which Erick sold his grapes is $7 + $2 = $9. For the 140 grapes, Erick collected 140 * $9 = $1260. From the sale of all of his fruits, Erick received $1260 + $960 = $2220. The final answer: 2220.
