Question 158595: a TOTAL INVESTMENT OF $13.500 IS DISTRIBUTED IN TWO ACCOUNTS, ONE THAT YIELDS INTREST AT AN ANNUAL RATE OF 5%, AND THE OTHER YIELDING INTREST AT THE ANNUAL RATE OF 7%. DETERMINE HOW MUCH IS INVESTED IN EACH ACCOUNT, IF THE TOTAL INTEREST AFTER ONE YEAR IS $855.
MY ANSWER
.07 + .05(13,500-X) = 855
.07X + 675-.05X = 855
-675 -675
.02X=180
.02X/.02=180/.02
X=9000
.07 X 9000 = 630
.05(13,500 - 9000)=4500

Question 161987: A 5% tax is imposed on the gross sales of liquor. How much tax is imposed on gross sales amounting to $2500.00?
We are dealing with money and percent, before we can combine them we must work with same type of number; so lets change the percent to decimal (money number)
5% is the same as .05 (i.e. 5%/100%=5/100=.05)
Now to find the answer to this we just multiply the amount with the sales tax
2500(.05)=125.00
