Answer:
6.76
Step-by-step explanation:
Let us create hypothesies as

(right tailed test for claiming most adults would erase)
Sample proportion p = 0.64
n = sample size = 582
Std error of proportion= 
P difference = 0.14
Test statistic = p difference/std error
= 6.755
=6.76
$19.50
-$15.50=
$4.00
1slice of pizza and 1soda is $4
so 2slices of pizza and 2 sodas is $8

Now you have 3 slices of pizza left
$7.50/3slices=$2.50
1slice of pizza is $2.50
