-18? I didn’t know - numbers were squared..
Answer:
<u><em>9 months</em></u>
Step-by-step explanation:
Principal= P= $1200
Rate=R= 15%
Interest= I= $135
Time= T= ?
I=P*R*T/100
135= 1200*15*T/100
135*100=18000*T
13500/18000=T
T= 0.75 years
T= 0.75*12= 9 months
Im not sure about the first one im probably wrong but im going with 12 and for the second one im going with 7 but im not positive with the answers <span />
