Answer 1

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

Sandra

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

substitute in the formula above

$75=2,500(r(1))$

solve for r

$r=75/2,500)$

$r=0.03$

Convert to percentage form

$r=0.03*100=3\%$

Ron

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

substitute in the formula of interest

$I=8,000(0.03*1)$

$I=\ 240$
