The total cost, if one drink costs $3 is $27.75
- Let the cost of a pizza be x
- Let the cost of a drink be y
If kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza, this expressed as x + 4y
Since a pizza costs $12.75, hence x = $12.75
The function becomes 12.75 + 5y
f(y) = 12.75 + 5y
To get the total cost if one drink costs $3, hence;
f(3) = 12.75 + 5(3)
f(3) = 12.75 + 15
f(3) = 27.75
Hene the total cost, if one drink costs $3 is $27.75

A) a team of 5 boys and 6 Girls
=7C5+ 8C6
= 21+28
= 49 teams
a team of 6 boys and 5 girls
= 7C6 + 8C5
= 7+56
= 63 teams
B) one girl is kept constant already and a guy has injury
Girls remaining to choose from 7
Boys remaining to choose from 6
= 1 +7C5 + 6C5
= 1+21+6
= 28 teams

Answer:
The surface area of the rectangular prism is 124in³
Step-by-step explanation:
To calculate the surface area of a rectangular prism we have to use the following formula:
a = area
w = width = 1in
l = length = 6in
h = height = 8in
A = 2wl + 2lh + 2hw
we replace the values that we know
a = 2 * 1in * 6in + 2 * 6in * 8in + 2 * 8in * 1in
a = 12in ² + 96in ² + 16in ²
a = 124in³
The surface area of the rectangular prism is 124in³
