Answer:
x=180
Step-by-step explanation:
Let us have x represent the entire mask collection
We know that 117 is 65% of his collection. We want to know the total number of masks he has
The equation we set up is:
117 is 65% of x: this translates to
117=0.65x, then we solve for x by dividing 0.65 by both sides
180=x
The total number of masks Josiah has is 180.
