Answer:
XXL = $19.75
Box of Breadstick = $3.5
Step-by-step explanation:
Given that:
Let :
cost per XXL pizza = x
Cost per box of bread stick = y
4x + 2y = 86 - - - (1)
6x + 4y = 132.50 - - - (2)
From (1): Divide (1) by (2)
2x + y = 43 - - - (3)
y = 43 - 2x
Substitute y = 43 - 2x into (2)
6x + 4(43 - 2x) = 132.50
6x + 172 - 8x = 132.50
-2x + 172 = 132.50
-2x = 132.50 - 172
-2x = - 39.50
x = $19.75
y = 43 - 2x
y = 43 - 2(19.75)
y = $3.5

Answer:
Emilia bought 28 sweets
Step-by-step explanation:
now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.
65-15+10=60 and now just do that simply ratio
E:Z=7:8
E+Z=7x+8x
60=15x
4=x
7x=28=Emilia
8x=32=Zakiah
Accuracy test:
(28+15)+(32-10)=65
28 is 4•7 and 32 is 4•8
