Rachel has been given $1000 to put into a savings account. She earns 2% simple interest every month. Rachel hopes to buy a car in two years. Help Rachel determine whether she
will have enough money if the car will cost $1500.

She will not have enough. She will only have $1480.

Step-by-step explanation:

The formula for simple interest is A=P(1+rt)

A=final amount

P=initial amount

r=interest rate per month

t=time in months

A=1000(1+(0.02)(24))=1480

Rachel will not have enough money after two years (24 months.)

Hope that helps!

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

is there a question here?
