Start by writing an equation using what the question says. Grugs apples and pears = 8329 * (0.01 * (50 + 90)). It’s asking for pears and apples, so add them first. Then find 1/100 of that number by multiplying it by 0.01. Finally, multiply that number. When simplified, it’s solved like
Grugs apples and pears = 8329 * (0.1 * (140))
= 8329 * 1.4
= 11660.6
So either 11661 or just 11660 apples depending on if you’re supposed to round or not.
