Express the given quantity in terms of the indicated variable. The perimeter (in cm) of a rectangle that is 3 cm longer than it is wide; w = width of the rectangle (in cm) A rental company charges $85 a day and 60 cents a mile for renting a truck. Michael rents a truck for 4 days, and his bill comes to $370. How many miles did he drive

Solution

1) perimeter 3cm + width ft

width =w ft

Perimeter = 3+w ft

2)Company charges rental ---$85 a day

So, for four days rental -----4*$85 = $340

Total bill = $370

Charges for total no. miles = 370 -340 = $30 = 30*100 cents = 3000 cents

Per mile charge= 60 cents

So, no. of miles driven = 3000/60 = 50 miles
