Carl bought 6 hot dogs and 5 drinks and paid $25.10 Susan purchased 6 hot dogs and 3 drinks and was charged $20.10 what is the cost of 1 hot dog in the cost of 1 drink?

Let x = the unknown cost of a single hot dog and y = the unknown cost of a single soft drink. We have two unknowns so we need two equations to find them.

Equation 1 - 10 hot dogs and 5 soft drinks cost $35; that is 10x + 5y = 35

Equation 2 - 7 hot dogs and 4 soft drinks cost $25.25; that is 7x + 4y = 25.25

First let's re-write equation 1 to solve for y:

10x + 5y = 35

5y = 35 - 10x (subtract 10x from both sides)

y = 7 - 2x (divide both sides by 5)

Next, let's substitute 7 - 2x for y in equation 2:

7x + 4y = 25.25

7x + 4(7-2x) = 25.25

7x + 28 - 8x = 25.25

-x + 28 = 25.25

x - 28 = -25.25

Solve for x, the cost of a single hot dog. Once you have that, use y = 7 - 2x to find the cost of a single soft drink.

step-by-step explanation:

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
