Suppose a refrigerator sells for $700 per and costs $85 a year for electricity. write the expression for the cost to buy and run the refrigerator for x years?

Cost of refrigerator = $700

Cost of electricity per year = $85

So cost of electricity for x years = $85x

Run the refrigerator for x years

Total cost to buy and run the refrigerator for x years = cost of refrigerator + cost of electricity for x years

Total cost to buy and run the refrigerator for x years = 700 + 85x

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
