Angela and neil are going to the movies they each bought a medium popcorn and neil got a small soft drink angela had a $10 gift certificate to put toward the cost and neil paid the rest which came to $19.30 a movie ticket costs $9 and a medium popcorn cost $4.40 how much does a small soft drink cost at the theater

The cost of small soft drink is $2.50.

Step-by-step explanation:

Cost of 1 medium popcorn = $4.40

Cost of 1 small of drink =x

Cost of 1 movie ticket = $9

Cost of 2 medium popcorn =2 × $4.40 = $8.80

Cost of 1 soft drink =1 × x =x

Cost of 2 movie tickets = 2 × $9 = $18

Amount of gift certificate, A = $10

Total amount of bill ,T= $19.30

T = $8.80 + x + $18 - A

$19.30 = $8.80 + x + $18 - $10

x = $19.30 - $8.80 - $18 + $10

x = $2.50

The cost of small soft drink is $2.50.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
