marsha deposited $9,500 into a savings account 3 years ago. The simple interest rate is 5%. How much money did marsha earn in interest?

$ 10, 925

Step-by-step explanation:

Interest = P( 1 + rt)

9500 { 1 + ( 0.05 x 3 ) }

= 9500 x 1.15

= $ 10,925

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.

the last choice
