Work Step by Step

a. Business is only in operation for 1 year... This is impossible to solve as the business hasn't been in operation for over 5 years. b. t=25 $P=-3(25)+50$ $P=-75+50$ $P=-25$ $P=0$ because you can't have a negative %. c. P=35 $35=-3(t)+50$ $35-50=-3(t)$ $-15=-3(t)$ $-15\div-3=t$ $t=5$ so 5+5=10
