A customer borrowed $2000 and then a further $1000 both repayble in 12 months. What would he have saved if he had taken out one
RSB [31]

A customer borrowed $2000 and then a further $1000 both repayble in 12 months. What would he have saved if he had taken out one loan for $3000 repayable in 12 months?

He took two different loans, it charged him loan processing fee twice, two-time documentation process, and of course, extra time spent for second loan. Instead, he could take single loan of $3000 with one-time processing fee, one-time documentation process, and time-saving also.

The length of a rectangle is five times its width. If the area of the rectangle is 320 cm^2, find its perimeter.
olchik [2.2K]
A = LW
A = 320
L = 5W

320 = W(5W)
320 = 5W^2
320/5 = W^2
64 = W^2
sqrt 64 = W
8 = W

L = 5W
L = 5(8)
L = 40

so the length (L) = 40 cm and the width (W) = 8 cm

P = 2(L + W)
P = 2(40 + 8)
P = 2(48)
P = 96  <=====
