Hope this helped
Your equation is a little messed up comment me the equation you need help with
Im pretty sure is b) 83 pizzas because 83 times 7.25 is equal to 601.75 and then if you subtract that by 425 you get 176.75
I = PRT/100
P = Principal, R = Rate, T = Time
I = 1500 * 7.5 * 1.5 /100
I = 168.75
Interest owed = $168.75
