Write a piecewise function that models each telephone billing plan. Then graph the function.$60 per month buys 450 minutes. Additional time costs $0.35 per minute.

Answers

Answer 1

Answer:

if 0 < x ≤ 450, y = $60.

if 450 < x ; y = $60 + (x - 450min) × $0.35

the calculation is as follows:

Here x will represent the number of minutes.

so if 0 < x ≤ 450, y = $60.

And,

if 450 < x ; y = $60 + (x - 450min) × $0.35

where we use (x - 450) ×$0.35 since any minute after the 450 minute mark is considered an extra time.

Answer 2

Answer:

Answer: if 0 < x ≤ 450, y = $60.

if 450 < x ; y = $60 + (x - 450min)*$0.35

Step-by-step explanation:

Here x will represent the number of minutes.

with $60 you have 450 minutes, and you must pay 60 regardless of how much minutes you use.

so if 0 < x ≤ 450, y = $60.

now, if you call for more than 450 minutes, you get an additional of $0.35 per minute, then we have:

if 450 < x ; y = $60 + (x - 450min)*$0.35

where we use (x - 450)*$0.35 because any minute after the 450 minute mark is considerated an additional time.

So our piecewise function is:

if 0 < x ≤ 450, y = $60.

if 450 < x ; y = $60 + (x - 450min)*$0.35

you spend $50 on a meal for you and your friends. graph the equation 1.5y+4x=50. y =number of sandwiches bought and x= number of drinks.

Answers

Start by listing this until you see that X+Y = 50
X can equal: 4,8,12,16,20,24,28,32,36,40,44
Y can equal: 1.5,3,4.5,6,7.5,9
So...
X=11
Y=4
so... 4 sandwiches were bought, and 11 drinks.

Answer:4 sandwhiches and 11 drinks
