John took out a loan for 18,550. To pay it back he will make 60 monthly payments of 389. How much will he pay in interest?
Debora [2.8K]

Answer:

He paid an of 4790

Step-by-step explanation:

If John took a loan of 18550

Then in 60 months, we will pay back 389 multiply by 60

389 × 60 = 23340

Therefore he paid an interest of 23340 minus 18550, that is

23340 - 18550 = 4790

Identify the percent of change as an increase or a decrease. 50 pounds to 35 pounds. Find the percent of change.
Solnce55 [7]
Since it starts at 50 and goes to 35....it is a decrease since the amount is going down, or getting smaller.  To find the percent, first find the difference 50-35 = 15; then divide by the initial amount of 50.  So, 15/50 = 0.3, and then convert that to a percent by multiplying by 100.  Therefore the percent decrease is 30%
