Answer:
He would save $4.75.
Step-by-step explanation:
Without the pass,
In a month, Arnold has to spend: $2.50 x 20 = $50
With the pass,
In a month, Arnold has to spend: $45.25
So, Arnold may save: $50 - $45.25 = $4.75 if he has a monthly pass.
I would say A but I'm not sure
Sry if I' m wrong <3
-21 - (-14) = <u>-21</u> + <u>14</u> = <u>-7</u>
A - and a - make a +. So -21 - (-14) makes -21 + 14. Solve to get -7.
Hope it helps!
