Acar 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?

10x + 15y = 980

Step-by-step 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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
