A 4-story office building has cubicles for 309 +336 + 301 + 326 workers. While one floor is closed for repairs, the office has cubicles for 309 + 301 + 326 workers. How many cubicles are there on the floor
that is closed? Explain.
There is/are cubicle(s) on the closed floor. The second expression is the same as the first except
that
(Type a whole number.)

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.
