Phones-R-Us charges $16.95 per month and $0.05 per text message. Awesome Wireless charges $22.95 per

Dima020 [189]

Answer:

$S \leq 200$

Step-by-step explanation:

Given

Phone R-Us= $16.95 + $0.05 per SMS

Awesome Wireless = $22.95 + $0.02 per SMS

Required

Determine the number of SMS such that Awesome Wireless is greater or equal to Phone R-Us

Represent the SMS with S

For Phone R-Us, we have:

$SMS = 16.95 + 0.05S$

For Awesome Wireless, we have:

$SMS = 22.95 + 0.02S$

For Awesome Wireless is greater or equal to Phone R-Us, we have:

$22.95 + 0.02S \geq 16.95 + 0.05S$

Collect Like Terms

$0.02S - 0.05S \geq 16.95 - 22.95$

$-0.03S \geq -6$

Solve for S

$\frac{-0.03S}{-0.03} \geq \frac{-6}{-0.03}$

$S \leq 200$

<em>Hence: for Awesome Wireless to cost more or equal to Phone R-Us, the number of SMS must not exceed 200</em>

Sophie invested 5,000 into an account that will increase in value by 2.3% each year. Write a function to model this situation, t

Zarrin [17]

Answer:

$6725

Step-by-step explanation:

Given data

Princiapal= $5000

Rate=2.3%

Time= 15years

The function that will model this situation is given as

A=P(1+rt)

The above function is a simple interest function

Substitute our data we can find the amount A

A=5000(1+0.023*15)

A= 5000(1+0.345)

A=5000(1.345)

A=5000*1.345

A=$6725

Hence the value of the investment after 15 years is $6725
