The total interest he will be charged is $37.45.

Step-by-step explanation:

Chargers 17% interest on any charges not paid at the end of the month.

Charge of 1,630.58

$1,410.28 paid.

$1,630.58 - $1,410.28 = $220.30 unpaid

So, 17% will be charged the 220.30 unpaid.

0.17*220.30 = 37.45

The total interest he will be charged is $37.45.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
