Answer:
0.21 square meter
Step-by-step explanation:
Area of the section of wall = 1 square meter
Dimension of part of mural completed = 
meter by 
meter
Part of the mural completed = Area of the rectangular part of mural completed
But,
Area of a rectangle = length x width
So that,
Part of the mural completed = length x width
= x
= 
= 0.2083
Part of the mural completed = 0.21 square meter
The part of the mural that has been completed by Beverly is 0.21 square meter.

Answer:
The price of a package of chocolate chip is $13.25
The price of a package of gingerbread is $17.18
Step-by-step explanation:
11x + 12y = 352
10x +8y = 270
Let "x" be the price of a package of chocolate chip.
Let "y" be the price of a package of gingerbread.
11x + 12y = 352(Multiply the 1st row by 10)
10x +8y = 270 (Multiply the 2nd row by 11)
-------------------
110x + 120y = 3520
110x +88y = 2970
--------------------------
3y = 550
y =550/3
y = 17.1875
The price of a package of gingerbread "y" is $17.18
Let's pick the first equation "110x + 120y = 3520"
110x + 120y = 3520
110x+ 120(17.1875)= 3520
110x+2062.5=3520
110x=3520−2062.5
110x=1457.5
x= 1457.5/110
x=13.25
The price of a package of chocolate chip is $13.25
