OA. 43%
OB. 30%
OC. 36%
OD. 70%

Answer 1

Your answer would be B.
`30`%

Explanation:

To figure out the decrease, you would first subtract the two numbers.

`1053 - 737.1 = 315.9`

Next, you would multiply the number by
`1053`.

`(315.9)/(1053) = .3`

Then, you would multiply that by
`100`.

`.3 * 100 = 30`

The answer would be
`30`%.

`1053 * .3 = 315.9`

`1053-315.9 = 737.1`
