In the attached image you can find both quantities in a line 4 being less than 10. To have the absolute value equation we note that 7 is equidistant 3 units from 4 and 10 or another way to figure this out is 4+10/2=7 therefore the equation can be written as |d-7|=3
<em>Hi There!!</em>
B = 1/2A + 30
C = 3/2A + 20
B = C
1/2A + 30 = 3/2A + 20
30 - 20 = 3/2A - 1/2A
10 = A
B = 1/2A + 30
B = 1/2(10) + 30
B = 5 + 30
B = 35
C = 3/2A + 20
C = 3/2(10) + 20
C = 15 + 20
C = 35
type A cabinets produced was 10
type B and type C cabinets produced were both 35
<em>Good Luck!!</em>
