Written an alternate way it is x^2/3 • 5x^3/3 (because 5x is to the power of one and in order to add fractions, you have to have the same denominator). So when you multiply the like terms, you add the exponents (2/3 and 3/3).
First, multiply the 1,500 by 4.3% to come up with $64.50 every three months (the question says compounded quarterly).
$64.50 x 4(quarters in a year) = $258.00 per year
$258.00 x 6 years = $1,548.00
$1,500.00 + $1,548.00 = $3,048.00 balance after six years
Mrs. Rodriguez gives 35 minutes, and if Mr. Beach gives 10 minutes less, than he gives 25 minutes. If Mrs. Johnson gives twice what Mr. Beach gives, she gives (25 x 2) 50 minutes.
add these all together (25 + 35 + 50) to get 110 minutes !
First you divide 380 by 100 to get what 1% is, (3.8) and then you multiply by 18 to give you 18%. The answer is 68.4, so add that to 380 and you'll have the final answer of 448.4.
