• She orders 170 black pens.
• She orders 120 blue pens.
Which equation can be used to find r, the number of red pens Ms. Karone

350 - 170 + 120 =r

350 + 170 – 120 =r

Answer:

Last equation 350 - 170 - 120 = r

Step-by-step explanation:

So if she ordered 350, and we already know 170 + 120 for black and blue pens. So we add 170 and 120 to get 290. So we subtract 290 from 250 and get 60. So the equation is 350 - 170 - 120 = r. Brainliest please!
