Answer:
Equations:
a + b = 19
a = b + 2
a = Money that spent Laura
b = Money that spent Laureen
then:
(b+2) + b = 19
2b + 2 = 19
2b = 19-2
2b = 17
b = 17/2
b = 8.5
a = b + 2
a = 8.5 + 2
a = 10.5
Check:
10.5 + 8.5 = 19
At first Divide the figure into two rectangles, I and Il
Area of figure l is ~
Area of figure ll is ~
Area of whole figure = Area ( l + ll )
that is equal to ~
1/2bh
1/2b4 = 18
b4= 36
b= 9 yards
