Question

Answer 1

Answer think that it I s500$

Step-by-

Answer 2

Therefore, Sal spent 50 minutes on his homework

Explanation:

Let x be the total number of minutes Sal spent in doing his homework

22% of x = 11 minutes

`(22)/(100)` × x = 11

`(22x)/(100)` = 11

Multiply both-side of the equation by 100

`(22x)/(100)` × 100 = 11×100

On the left-hand side of the equation 100 will cancel-out 100

Our equation becomes;

22x = 1100

Divide both-side of the equation by 22 to get the value of x

`(22x)/(22)` =
`(1100)/(22)`

(On the left-hand side of the equation 22 at the numerator will cancel-out 22 at the denominator leaving us with just x while on the right-hand side of the equation 1100 will be divided by 22)

x = 50 minutes

Therefore, Sal spent 50 minutes on his homework
