Alicia has invented a new app that two companies are interested in purchasing for a 2-year contract. company a is offering $10,000 for the first month and will increase the amount each following month by $5000. company b is offering $500 for the first month and will double their payment each following month. for which monthly payment will company b's payment first exceed company a's payment?

Month 8

In this month Company B's plan will pay $64,000 versus $45,000 from Company A.

Step-by-step explanation:

Start by calculating the monthly payments for both plans.

20$105,000$262,144,000

21$110,000$524,288,000

22$115,000$1,048,576,000

23$120,000$2,097,152,000

24$125,000$4,194,304,000

8th Month

Step-by-step explanation:

We will calculate the payments by both the method as shown below

Company A

$10,000 + $ 5000 = $ 15000

$ 15000 + $5000 = $20,000

$20,000+ $5000 = $25,000

$25,000 + $5000 = $30,000

$30,000 + $5000 = $35,000

$35,000 + $5000 = $40,000

$40,000 +  $5000 = $45,000

$45,000 + $5000 = $45,000 = $ 50,000

$ 50,000 + $ 5000 = $ 55,000

Company B

$ 500

2 x $ 500 = $1000

2 x $1000 = $2000

2 x $2000 = $4000

2 x $4000 = $8000

2 x $8000 = $ 16,000

2 x $ 16,000 = $ 32,000

2 x $ 32,000 = $ 64,000

2 x $ 64,000 = $128,000

Thus, it is the 8th month during which Company B's payment first exceed Company A's payment
