Achain saw rental for $12 a day. a sharpening fee of $5 is charged for each rental. write an equation for the number of dollars (y) that must be paid to rent a chain for x days. how many days can one rent a chain saw for a cost of $125?
y= 12x+5 and it would be 10 days.
+5 = each rental
x= # of days
125= 12x+5; x=10
21.6 is the payment amount from mom to emily
payment / unit distance = total payment/total distance
givenspayment =0.90 unit distance = 0.75 milestotal payment = xtotal distance = 18 miles
0.9/0.75 = x / 18 multiply both sides by 18
0.9 * 18/0.75 = x * 18/18 simplify.
16.2 / 0.75 = x simply the left
21.60 = x
the answer would be 8 do you need an explanation?
