Answer:
Mr. Hildebrant planned to spend $95 in the gift shop.
Step-by-step explanation:
We want to find 80% of $? equals $76.
We can write an equation to help us solve for <u>x</u>, <u>the money that Mr. Hildebrant planned to spend in the gift shop</u>.
Divide both sides of the equation by .80.
Mr. Hildebrant planned to spend $95 in the gift shop.
We know, Distributive property tells: a(b + c) = ab + bc
So, 9.78(4.3x + 5.15) = 42.054x + 50.367
In short, Your Answer would be Option B
Hope this helps!
