Question 176219
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:


{{{T = 110 + 6c}}}


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:


{{{T = 110 + 6c}}}


Add -110 to both sides:


{{{T - 110 = 6c}}}


Divide by 6:


{{{(T - 110)/6 = c}}}


Now substitute 500 for T and do the arithmetic.
