100 mL of the drink is coffee
The total amount of drink is 100 mL +400 mL = 500 mL. Then the fraction that is coffee is ...
coffee/total = (100 mL)/(500 mL) = 1/5 = 1/5 × 100% = 20%
20% of Donna's drink is coffee.
Find the interest earned in 1 year and divide it by 12 (number of months per year)
simple interest=principal times rate times time
so we have 1250 principal (amount invested)
rate is 5% or 0.05
time is 1 year
in 1 year, he earns 1250 times 0.05 times 1 or $62.5 per year
divide by 12
62.5/12=5.2083333333333333333333333333333
earns about $5.21 per month in interest
You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
