Gavin and caleb go to the movie theater and purchase refreshments for their friends.

gavin spends a total of $22.25 on 2 bags of popcorn and 3 drinks.

caleb spends a total of $39.00 on 12 bags of popcorn and 4 drinks.

write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink.

popcorn=$1

dring=$6.75

Step-by-step explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25        

12*P + 4D = 39.00

12P + 18D = 133.5      

- 14D = - 94.50        

-14D/-14 = -94.5/-14

D = 6.75

6.75x3=20.25

20.25+2P=22.25

P=1

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
