Angela and neil are going to the movies. they each bought a medium popcor, and neil got a small soft drink. angela had a $15 gift certificate to put towards the cost, and neil paid the rest, which came to $23.50. a movie ticket costs $13, and a medium popcorn costs 4,50. what was the cost for a soft drink? asap

The cost for a soft drink was $3.50

Step-by-step explanation:

Angela has a $15 gift certificate.

Total cost for the popcorn and drink and movie tickets = $15 + $23.50 = $38.50

The cost of 2 movie tickets = $13 x 2 = $26

The cost of 2 popcorn = $4.50 x 2 = $9.00

Now we have to find the cost for a soft drink.

Let "x" be the cost for a soft drink.

Total cost = x + The cost of 2 popcorn + The cost of 2 tickets

$38.50 = x + $9 + $26

$38.50 = x + $35

x = $38.50 - $35

x = $3.50

So the cost for a soft drink was $3.50

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
