Answer:
we take each number as x = 2x 3x 4x (2x)³+(3x)³+(4x)³=33957 8x³+27x³+64x³=33957 99x³=33957 x³=33957÷99 =∛343 x=7 2x=2×7=14 3x=3×7=21 4x=4×7=28 =the three numbers are 14,21,28
This is easy. You all need to do this: 100÷2 it equals 50. You need to subtract one 50 from either Caroline/Mohamed(Take Caroline's for example) Caroline = 50-16=34. Then you add 16 to 50(Mohamed's) 50+16=66 Therefore, Caroline sold 34 tickets, however, Mohamed sold 66 tickets. To prove: add 66+34 66+34=100
Mohamed sold 58, and Caroline sold 42.
