Answer:
Kayleigh will have a total of $4608.
Step-by-step explanation:
First, you use the formula, I=PRT (Interest=Principal, Rate, Time), then you distribute the numbers: (I=4500x0.8%x3) when you multiply them all, you get $108, then you lastly add 108 to 4500, and you get your final answer of $4608.
8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4
-- I've decided to name the unknown number ' Q ', because I can.
-- The product of 25 and the unknown number is 25 Q .
-- The quotient of that product and 45 is 25 Q/45 .
-- We're told that this quotient is -65 .
25 Q / 45 = -65 .
