$15.75
2 x 7.5 = 15
0.10 x 7.5 = 0.75
15 + 0.75 = $15.75
Hope this helped

Marc maxwell took out a simple interest loan at 13% interest for 12 months. his previous balance is $2,681.04. what is the final

V125BC [204]

Simple interest is given by:
S.I.=(PRT)/100
where:
P=principle
R=rate
T=time
from the question:
P=2681.04
R=13%
T=12 months=1 year
thus;
S.I=(2681.04×1×1.3)/100
=$34.85352
The total amount payable will be:
Total amount=principle+interest
=34.85342+2681.04
=$2715.90 This is approximately equal to $2,710.08

B. What number is equal to 280 tenths + 19 thousandths?<br><br> HELP!!

Kaylis [27]

The number that equals 280 tenths + 19 thousandths is 28.019

<h3>How to determine the number?</h3>

The statement is given as:

280 tenths + 19 thousandths

Rewrite the terms of the expression as fractions

So, we have

280/10 + 19/1000

Evaluate the quotients

28.0 + 0.019

Add both numbers

28.019

Hence, the number that equals 280 tenths + 19 thousandths is 28.019
