Angela and neil are going to the movies. they each bought a medium popcorn, and neil got a small soft drink. angela had a $5 gift certificate to put toward the cost, and neil paid the rest, which came to $27.90. a movie ticket costs $10.00, and a medium popcorn costs $5.50. how much does a soft drink cost at the theater?
$1.90
$7.40
$2.90
$17.40

Let us assume the cost of a soft drink = x dollars
Value of the gift certificate that Angela had = $5
Cost of the movie ticket = $10
Cost of a medium popcorn = $5.50
Then
27.90 + 5 = 2(10) + 2(5.50) + x
32.90 = 20 + 11 + x
32.90 = 31 + x
x = 1.90 dollars

From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option or $1.90.

The slope of the function is 0.5.
