Suzanne bought 50 apples at the apple orchard. she bought 4 times as many red apples as green apples. how many more red apples than green apples did suzanne buy?

x = Number of green apples

4x = Number of red apples.

x + 4x = 50

5x = 50

x = 10 Green apples

4x = 4 * 10 = 40 Red apples

40 - 10 = 30 more red than green apples

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
