Answer:
1: $1.50
2: $3.00
4: $6.00
5: $7.50
6: $9.00
7: $10.50
8: $12.00
9: $13.50
Step-by-step explanation: To answer this problem you need to divide $4.50 by 3. When you do that you get $1.50 per pound of gummy bears. Then you can either add $1.50 to each amount or multiple them by the x value. Then graph the numbers you get.
Answer:
(2) If 300 lunches were sold, then 120 chose tacos.
Step-by-step explanation:
We can evaluate each option and see if it makes it true.
For 1: If 200 lunches were served, 10 more students chose pizza over hotdogs.
We can find how many pizzas/hotdogs were given if 200 lunches were served by relating it to 100.
20% chose hotdog, which is
. Multiply both the numerator and denominator by two:
- so 40 students chose hotdogs.
Same logic for pizza: 30% chose pizza -
so 60.
60 - 40 = 20, not 10, so 1 doesn't work.
2: If 300 lunches were sold, then 120 chose tacos.
Let's set up a proportion again. 40% of 100 is 40.
![\frac{40}{100} = \frac{40\cdot3}{300} = \frac{120}{300}](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B100%7D%20%3D%20%5Cfrac%7B40%5Ccdot3%7D%7B300%7D%20%3D%20%5Cfrac%7B120%7D%7B300%7D)
So 120 tacos were chosen - yes this works!
Hope this helped!

Answer:
y = 1/2x - 4
Step-by-step explanation:
y - (-2) = 1/2(x - 4)
y + 2 = 1/2x - 2
y = 1/2x - 4
Answer:21
Step-by-step explanation: If the formula I've used was right. All you had to do was use the percentage of the children who liked science more which is 35% and change it into a decimal like 0.35 and multiply that with 60 and your answer is 21!
