Question

Jake is comparing the prices of two mattress cleaning companies. Company A charges $30 per mattress and an additional $13 as service charges. Company B charges $28 per mattress and an additional $15 as service charges.
Part A: Write equations to represent Company A and Company B's total mattress cleaning charges for a certain number of mattresses. Define the variable used in the equations.
Part B: Which company would charge less for cleaning 4 mattresses? Justify your answer.
Part C: How much money is saved by using the services of Company B instead of Company A to clean 7 mattresses?

HELPP!!!!!!! @skullpatrol @sisco0123 @dan815

Answer 2

let the no of mattresses are x
then for company A : \[t_a=30x+13\] here \[t_a\] for total cleaning charges for company A
now for company B:\[t_b=28x+15\] where \[t_b\] are total cleaning charges for company B
moving onto 2nd part of your question
for 4 mattresses insert x=4 in both eqns
\[t_a=30.4+13=120+13=133\]
\[t_b=28*4+15=127\]
obviously company B is charging less for 4 mattresses
for 3rd part
again put x=7 in both eqns
\[30*7+13=210+13=223=t_a\]
\[28*7+15=211=t_b\]
so net saving would be \[223-211=$12\]
