Question 171612: The formula I=PRT
23.If I owe $84.00 in interest after four years on a loan at 6% interest, how much did I originally borrow?
32. The difference in age between two churches is 154 years.
a. How old is the older church if the newer church is 226 years old.
is the answer 380?
b. If the newer church was built in the year 1650, what year was the older church built?
is the answer 1496?
44.About 71.5 % of the drivers involved in fatal motor vehicle accidents are male. In 1999, 30,400 male drivers were involved in fatal motor vehicle accidents. How many accidents were there in all?
Of last year's graduates from a local high school, 182 responded to a higher education survey. That was 28% of the graduating class. How many people graduated from that school last year?

You can put this solution on YOUR website! The formula I=PRT
23.If I owe $84.00 in interest after four years on a loan at 6% interest, how much did I originally borrow?
84 = P*0.06*4
84 = P*0.24
P = 84/0.24
P = $350.00
========================
32. The difference in age between two churches is 154 years.
a. How old is the older church if the newer church is 226 years old.
is the answer 380?
Ans: newer + 154 = older
226 + 154 = older
older = 380
You are correct
=========================
b. If the newer church was built in the year 1650, what year was the older church built?
is the answer 1496?
newer - 154 = older
1650 - 154 = older
older = 1496
You are correct
==========================
44.About 71.5 % of the drivers involved in fatal motor vehicle accidents are male. In 1999, 30,400 male drivers were involved in fatal motor vehicle accidents. How many accidents were there in all?
Let "x" be the total number of accidents.
Then 0.715x = 30,400
x = 30400/0.715
x = 42517.48
Rounding down you get 42517
=================================
Of last year's graduates from a local high school, 182 responded to a higher education survey. That was 28% of the graduating class. How many people graduated from that school last year?
0.28x = 182
x = 182/0.28
x = 650
==================================
