There are 5 slides, i've provided image for them all i need help with it. if your going to answer write it in order from slide 1-5 so it's easier to understand.

Slide 1.

Part A.

1. Band A:  y = 600

2. Band B: y = 1.25x + 350

Part B.

200 students.

Slide 2.

Part A.

Fixed cost = $150

Rate per student served = $6

Part B.

To figure the cost/person, look at the change in cost divided by the change in attendance.

For 100 students, cost = $750.

For 150 students, cost = $1050.

Change in cost = $300

Change in students = 50

Cost per additional student = 300/50 = $6

Assuming the costs are linear, then the price charged for 100 students reflects the cost per student + a 'fixed cost' that applies to the order as a whole.

100 * 6 = $600, so the fixed cost is 750-600 = 150.

We can check this notion by substituting in the other equation.

Does 150*6 + 150 = 1050? Yes.

150*6=900

900+150 = 1050.

Slide 3.

Part A.

She can choose either band, with $9.75 per ticket, if 200 students attend

Part B.

Check the cost using band A and 200 people, including food

600 + 150 + (6*200) =

600 + 150 + 1200 = $1950

Cost per ticket: = 1950/200 = $9.75

Cost using band B, 200 people, including food:

350 + 1.25(200) + 150 + (6*200) =

350 + 250 + 150 + 1200 = $1950

Cost per ticket: 1950/200 = $9.75

This means that Paula can choose either band, and the ticket cost will be the same.

Slide 4.

Part A.

Cost per ticket: $8.50 (of Band A, since it is the cheaper one)

Part B.

Check the cost using band A and 300 people, including food

600 + 150 + (6*300) =

600 + 150 + 1800 = $2250

Cost per ticket: = 2250/300 = $8.50

Cost using band B, 200 people, including food:

350 + 1.25(300) + 150 + (6*300) =

350 + 375 + 150 + 1800 = $2675

Cost per ticket: 2675/300 ≈$8.92

Which means that in this scenario is Band A is less expensive.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

answer:     true
