Answer:
185
Step-by-step explanation:
Let x represent the total number of boxes of cookies sold
We know Emily sold 40% of the total boxes for the fundraiser
The number of boxes would be represented as:
40/100x=0.40x
Since 74 boxes were sold, then the equation would be~
0.40x=74
0.40x 74
------- = ------
0.40 0.40
x=185
