Answer 1

$151.00 was earned over the 3 days.

Explanation:

First Day:

.90(50)

Second Day:

50 + .06(50)

Third Day:

50 - .14(50)

.9(50) + 50 + .06(50) + 50 - .14(50)

45 + 53 + 43

141

Answer 2

They made 45 dollars the first day, 53 dollars the second day, and 43 dollars the third day. In total the made 141 dollars.

Explanation:

For the first day you multiply the goal amount by the decimal or fraction that represents the percentage to get your answer. So it would be:

• 50 x 0.90 = 43

For the second day you do the same as above, but once you get the answer to that step, you add fifty to it. You can also do it all in one step. It would look like:

• 50 x 0.06 = 3

• 3 + 50 = 53

OR

• 50 + (50 x 0.06) = 53

For the third day you would do the same as you did for the first day, then you would take that answer and subtract it from fifty. You can do this all in one step too. It should look like this:

• 50 x 0.14 = 7
• 50 - 7 = 43

OR

• 50 - (50 x 0.14) = 43

Then to get your final answer, you would just add all of the days up like this:

• 45 + 53 + 43 = 141

So your answer would be 141 dollars, or $141.00
