Answer:

Marsha must pay in 2 years [tex]\$9,100[/tex]

Step-by-step explanation:

we know that

The simple interest formula is equal to

[tex]A=P(1+rt)[/tex]

where

A  is the amount of money to pay

P is amount of money borrowed  

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=2\ years\\ P=\$7,000\\ A=?\\r=15\%=15/100=0.15[/tex]

substitute in the formula above

[tex]A=7,000(1+0.15*2)[/tex]

[tex]A=7,000(1+0.30)[/tex]

[tex]A=7,000(1.30)[/tex]

[tex]A=\$9,100[/tex]

therefore

Marsha must pay in 2 years [tex]\$9,100[/tex]
