Answer :

The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50

Elimination method was used.

Step-by-step explanation:

Let,

Cost of one large pizza = x

Cost of one breadstick = y

According to given statement;

4x+y=34.46    Eqn 1

2x+y=18.48     Eqn 2

Subtracting Eqn 2 from Eqn 1

[tex](4x+y)-(2x+y)=34.46-18.48\\4x+y-2x-y=15.98\\2x=15.98[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{15.98}\\x=7.99[/tex]

Putting x=7.99 in Eqn 2

[tex]4(7.99)+y=34.46\\31.96+y=34.46\\y=34.46-31.96\\y=2.50[/tex]

The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50

Elimination method was used.
