David and joe went to the pizzeria. David ordered 3 slices of pizza and 4 garlic knots and paid 10.65. Joe ordered 2 slices of pizza nd 10 garlic knots and paid 9.30. How much is the cost of each item

The cost of slices of pizza = x = $2.82

The cost of garlic knots = y = $0.55

Step-by-step explanation:

David and joe went to the pizzeria.

Let

The cost of slices of pizza = x

The cost of garlic knots = y

David ordered 3 slices of pizza and 4 garlic knots and paid 10.65.

3x + 4y = 10.65Equation 1

Joe ordered 2 slices of pizza nd 10 garlic knots and paid 9.30.

2x + 10y = 9.30 Equation 2

Hence:

3x + 4y = 10.65Equation 1

2x + 10y = 9.30 Equation 2

We solve using Elimination method:

Multiply Equation 1 by 2 and Equation 2 by 3 to eliminate x

3x + 4y = 10.65Equation 1 × 2

2x + 10y = 9.30 Equation 2 × 3

6x + 8y = 21.30Equation 3

6x + 20y = 27.9...Equation 4

Subtract Equation 4 from 3

12y = 6.6

y = $0.55

We solve for x using Equation 1

3x + 4y = 10.65Equation 1

3x + 4($0.55) = $10.65

How much is the cost of each item

3x + $2.2 = $10.65

3x = $10.65 - $2.2

3x = $8.45

x = $8.45/3

x = $2.8166666667

x = $2.82

The cost of each items

The cost of slices of pizza = x = $2.82

The cost of garlic knots = y = $0.55

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

don't give

take it once

try and try and you will not

happy to

pls mark as brainliest
