A computer technician charges a flat fee of $50 plus $25 per hour. On Monday, he worked on Aika's computer for 2 hours. On Tuesday, he worked on Aika's computer for 3 hours. Which expression(s) represents Aika's bill? Select all that apply.

The answer is D and E because since the technician worked for both 2 and 3 hours you would add them. In E, it is like distribution you would multiply both the 2 and 3 to get 50 and 75 and you would add them to get 125 then just add the 50 to get 175. You can choose to add for D to get 5 so 25 x 5 which would be 125 so 50 + 125 will get you your same answer as 175
