Answer:
$536.25
Step-by-step explanation:
First, you need to find what 7.5% of $2,200 is,
(2200/100)7.5=165
then to find how much interest has accumulated over 3 1/4 year you need to multiply the one-year interest rate by the 3.25
(165)3.25=536.25
This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.
So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.
There will be 40 mosquitoes after ten months.
2. $9.20 cause you multiply the price by the number of the sweets
