Question

four friends went to the coast on vacation and wanted to split the trip’s costs evenly between them. the house rental cost $400. the cleaning fee was $75 and they ordered pizza the first night for $25. how much should each friend contribute?
a $500
b $1.25
c $100
d $75

Explanation:

Step1: Calculate total cost

First, find the sum of all costs. The house rental is $400, cleaning fee is $75, and pizza is $25. So total cost $= 400 + 75 + 25$.
$400 + 75 + 25 = 400 + (75 + 25) = 400 + 100 = 500$.

Step2: Divide by number of friends

There are 4 friends, so each friend's contribution $= \frac{500}{4}$.
$\frac{500}{4} = 125$? Wait, no, wait, 500 divided by 4 is 125? Wait, no, 4*125=500. Wait, but the options: A is $500, B is $125, C is $100, D is $75. Wait, let's recheck. Wait, house rental $400, cleaning $75, pizza $25. Total 400+75=475, 475+25=500. Then 500 divided by 4 is 125. So each friend contributes $125. Wait, but let me check the options again. Option B is $125.

Wait, maybe I made a mistake? Wait, 4 friends. 400 +75 +25 = 500. 500 /4 = 125. So the answer should be B. $125.

Answer:

B. $125
