The correct answer is 56 chews
Explanation:
Step 1:
Realize that the sum of all percentages should add up to 100%. We will use this information to determine the percentage of the chews that are grape fruit. Let x be the percentage of the chews that are grape fruit, the following equation holds true,

Step 2
The next step is to solve equation (1) for the value of x to determine the percentage of the chews that are grape fruit. This is done as shown below,

We have determined that 35% of the chews are grape fruit chews.
Step 3
The next step is to compute 35% of 160 fruit chews to determine the number of grape fruit chews. This is done as show below,
