Step-by-step explanation:
Answer:
A
Step-by-step explanation:
let x= pizza y= soda
kay:
x+y=4
Mark:
6x+2y=18
From kay's equation
x= 4-y
substiute that into mark's
6(4-y)+2y=18
24-6y+2y=18
-4y= -6
y= 1.5
Plug in y= 1.5 in either equation to solve for x
x+1.5=4
x=2.5
So a pizza is 2.5 and a soda is 1.5
the answer must be A
