A number was added to 8.8. This result was then multiplied by 5 and that total was the divided by 0.5. If the quotient was 199, what was that number.

11.10

Step-by-step explanation:

Let x be the unknown number

[(x + 8.8) x 5 ] / 0.5 = 199

To find x,

first multiply both sides of the equation by 0.5

[(x + 8.8) x 5 ] = 99.5

Then divide both sides by 5

x +  8.8 = 19.9

Subtract 8.8 from both sides

x = 11.1

answer: -1
