Question

Suppose four friends each pay for a pair of socks and one 30-minute jump. The jump costs $10.50 per person. If they spend a total of $50, then the equation 4(10.50 + x) = 50 can be used to find the cost x of the socks. What is the cost to rent a pair of socks?

A) $7
B) $8
C) $9
D) $10

Answer 1

The cost to rent a pair of socks is $2.

Step-by-step explanation:

To find the cost to rent a pair of socks, we can solve the equation 4(10.50 + x) = 50 for x.

First, distribute 4 to both terms inside the parentheses: 42 + 4x = 50.

Then, subtract 42 from both sides: 4x = 8.

Finally, divide both sides by 4: x = 2.

Therefore, the cost to rent a pair of socks is $2.
