A small business just leased a new computer and color laser printer for three years. The service contract for the the computer offers unlimited repairs for a fee of $100 a year plus a $25 service charge for each repair needed. The company's research suggested that during a given year
86%of these computers needed no repairs,
9% needed to be repaired once,
4% twice.
1% three times,
and none required more than three repiar.
what is all the needed information to help solve and solve this problem?

What is the question? Is it whether the service contact should be purchased? To answer that, you need to know the average price of repairs without the contract. The way you have stated the problem, there is a service charge of $25 per repair even in the contract is purchased. You also say nothing about the color printer repair frequency and cost.

how do you solve the equation
9x 5y =4
my answer is y=9/5 + 4/5
is this correct
if so, i's having problems making a table of values.
