Answer:
Step-by-step explanation:
$19.50
-$15.50=
$4.00
1slice of pizza and 1soda is $4
so 2slices of pizza and 2 sodas is $8
$15.50-$8=$7.50
Now you have 3 slices of pizza left
$7.50/3slices=$2.50
1slice of pizza is $2.50
Answer:
each burger costs : $4.50
each slice of pizza costs : $2
Step-by-step explanation:
3 slices of pizza + 2 burgers = $15.50 ➡ 3p + 2b = $15.50
1 slice of pizza + 4 burgers = $20➡ 1p + 4b = $20
multiply second equation by -3 then add both equations up
-3p - 12b + 3p + 2b = $15.50 - $60 ➡-10b = -$44.50
b = $4.50 now use this value in the second equation to find the price of pizza slice
1p + 4×4.50 = $20 ➡1p = $2
