How much money would be in my account if I deposited $775 for 30 months at 19% interest?

$1197.21

Step-by-Step Explanation:

COMPOUND INTEREST FORMULA:

A = P(1 + r/n)^n(t)

775((1+(19/100))^2.5 = $1197.21

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
