Find the refund fraction for a 60-month loan if it is paid in full with 22 months remaining.

refund fraction is 0.138

Step-by-step explanation:

given data

loan time = 60 month

remaining time = 22 month

to find out

refund fraction

solution

we will apply here refund fraction that is

refund fraction = remaining time / loan time   1

refund fraction = 22 + 21 + 20 +  +1) / ( 60 + 59 + 58 + 57 + +1 )

refund fraction = ( 22 + 1 ) × 22/2  / ( 60 + 1 ) ×  60/2

refund fraction = 253 / 1830

refund fraction = 0.13825

so refund fraction is 0.138

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
