Jeff places a pineapple with a mass of 890 grams on a balance scale. He balances the scale by placing two oranges an apple and a lemon on the other side. Each orange weighs 280 grams. The lemon weighs 195 grams less than each orange. What is the mass of the Apple?
Accepted Solution
A:
(280 * 2) + (280 - 195) = 645 In order to balance it, both sides need to have the same mass. 890 - 645 = 245 grams is how much the apple weigh
