Justine received a bonus check from her work for $6000. she is going to deposit the money into her bank account that receives 5% simple interest. the account balance after year 5 is $4,500 $7,500 $6,300

Assuming the inteest is annual, since it's simple that means we just have to analyze:

, where r is our interest rate as a decimal, t is time, p is our principal investment and A is our ending value. So, in the context of our problem this becomes:

, which when evaluated by our trusty calculator becomes:

7657.68938,

which is rounded to 7500 in the problem.

the perimeter is increased by a factor of 2

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
