Ray’s weight increased by 11% in the last two years. If he gained 16.5 pounds, what was his weight two years ago?

Respuesta :

Diamori
11% = 16.5
1% = 16.5 / 11
= 1.5
100% = 1.5 * 100
= 150. His weight two years ago was 150 pounds.
Piinoy
x + (x * .11) = x + 16.5
2x * .11 = x + 16.5
Subtract x from both sides.
x * .11 = 16.5
Divide by .11 on both sides.
x = 150

Ray weighed 150 pounds two years ago.
