The formula for simple interest is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
Here, i = ($315) (0.015) (3) = $14.18 (answer)
Ultimately, it is impossible to solve an equation without two sides. If it was 2X=2, the answer would be X=1. But if it was 2X+2=0, the answer would be X=-1. The information given is impossible to work with,
Answer:
35.00
Step-by-step explanation:
4a+8p=220
2a+5p=130
if we want to add them we must multiply the 2nd equation by -2
4a+8=220
-4a-10p=-260
0=20
after plugging 20 in, the apples should cost 15
15+20=35
