Answer:
Each pizza costs $12.
Each drink costs $2.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the cost of each pizza.
y is the cost of each drinks.
The Talbot family got 2 pizzas and 4 drinks for $32.
This means that
The Martinez family got 3 pizzas and 8 drinks for $52.
This means that
Using the addition method, multiplying the first equation by -2.
-4x - 8y = -64
3x + 8y = 52
-4x + 3x - 8y + 8y = -64 + 52
-x = -12
x = 12
Each pizza costs $12.
2x + 4y = 32
2x + 4y = 32
4y = 32 - 2x
4y = 32 - 2*12
4y = 8
y = 2
Each drink costs $2.
Hmmm what is now discounted? well, let's assume it sells normally for 499 and is discounted today at 25%, how much is that?
well, if we take 499 to be the 100, how much is 25%?
now, applying the sales tax to the discounted price.
if we take 374.25 to be the 100%, how much is 6.5%?
so, the total cost will then be 374.25 + t.
