Write it in English, then translate to math:

Tara's total is $110 plus $6 times every customer. Let T mean total, and c mean the number of customers, then:

You can answer the second question by substituting 25 for c and doing the arithmetic.

To answer the third part, first solve your equation for c:

Add -110 to both sides:

Divide by 6:

Now substitute 500 for T and do the arithmetic.

Tara is a musician. She signs a contract with a local lounge to play a show for them on Friday night. The lounge manager agrees to pay $110 to reserve the night,plus an additional $6 for every customer,c,that comes in to hear her show.
Questions:
1.Write an equation that shows how much Tara will earn in total (e),depending on how many customers come to hear her show (c)?
E(c) = 110 + 6c
----------------------------------------
2.If 25 customers come,how much will Tara earn in total?
E(25) = 110 = 6*25 = 110 + 150 = $260
----------------------------------------
3.If Tara wants to earn at least $500,how many customers will need to attend?
110 + 6c >= 500
6c >= 390
c >= 65 (# of customers needed for Tara to make at least $500)
