Answer:

\$240

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

<em>Sandra</em>

t=1\ year\\ I=\$75\\ P=\$2,500\\r=?

substitute in the formula above

75=2,500(r(1))

solve for r

r=75/2,500)

r=0.03

Convert to percentage form

r=0.03*100=3\%

<em>Ron</em>

t=1\ year\\ I=?\\ P=\$8,000\\r=0.03

substitute in the formula of interest

I=8,000(0.03*1)

I=\$240
