The y-int. is found by setting x = 0: 3(0) + 2y = 7, or 2y = 7, or y = 7/2.
So the y-intercept is (0,7/2). You could also write "b=7/2."
5 more because Mary had double and it was 5
The formula to be followed for the calculation of simple interest is F = P (1 + in) where F is the future worth, P is the present worth, i s the annual interest rate and n is the number of years. In this case, F = $275 * (1+ 0.08*16) = $627. The interest earned is $627 - <span>$275 equal to $352.</span>
