Answer:
See below ~
Step-by-step explanation:
<u>Equation Plan A</u>
<u>Equation Plan B</u>
<u>Equating them</u>
- 40x + 860 = 100x + 200
- 60x = 660
- x = 11
- The plans will pay the same at 11 correct questions.
<u>Solving for y using x = 11</u>
- y = 100(11) + 200
- y = 1100 + 200
- y = 2300
- The amount they'll pay at that number of questions is $2,300
<u>Comparing both plans when x = 13</u>
- Plan A : 40(13) + 860 = 520 + 860 = $1,380
- Plan B : 100(13) + 200 = 1300 + 200 = $1,500
- As Plan B pays more, that is the plan you should choose
