8$ per hour

Step-by-step explanation

First, we need to find how many hours Naomi worked, total.

Simply add

Now we know that Naomi earned 54$ over 6.75 hours.

All we have to do to find the hourly rate is divide

Naomi earns 8$ per hour mowing lawns.

$8

Step-by-step explanation:

Set up an equation with the payrate ($/hr) as the unknown.

2.5 × R + 4.25 × R = 54

6.75 × R = 54 ; R = = 8

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.
