Answer: The equation would be 59.50 = 30 + .25x. You would solve by subtracting 30 from 59.50, and you get 29.5. Then dividing .25 by that, and you get 118. So you sent 118 texts. i think this is the answer good luck :D
At the start they both have 200?
I tried to include some explanations as well. Hopefully this helps.
Answer: 80 cookies
Step-by-step explanation: He had to bake 240 cookies and on Monday he baked have of them which is 120 cookies. Then on Tuesday he baked a third of the remaining so if the baked 120 and has to bake 240 he still has to bake 120 now 1/3 * 120 = 40 so he baked 40 cookies on Tuesday on Wednesday he still has to bake the reaming cookies so 120 + 40 = 160 and 240 - 160 = 80 so on Wednesday he has to bake 80 cookies.
