Question

A car wash business charges $10 per basic wash and $15 per ultimate wash. The total sales was $980 on a certain day. The variable x represents the number of basic washes and y represents the number of ultimate washes.

Which equation models this situation?

Answer 1

10x + 15y = 980

hope this helps^^

Answer 2

10x + 15y = 980

Explanation:

Here, x represents the number of basic washes and y represents the number of ultimate washes,

Since, the charge is $10 per basic wash and $15 per ultimate wash.

So, the total charges = ( 10x + 15y ) dollars

According to the question,

Total charge is $ 980,

⇒ 10x + 15y = 980

which is the required equation.
