A.The greatest possible sum of a and b can be 47 if the two integers are -1 and 48
B.Yes it is possible. The two integers are-3 and 16.
C. The least possible difference is -49 if the two integers are 1 and -48
I'll do 22 for you. 22, 24, 26, 28, and 30, are very similar to each other.
PROPORTIONS:
Draw it out.
5/7 = either c/6, or b/5.
I'll do c/6
5/7 = c/6
solve for c
7c=30
c=30/7
now do the same thing to the remaining side, b.
there!
A = 8B
A + B = 180
8B + B = 180
9B = 180
B = 20
A = 8 * 20 = 160
Sale price = original price - discount
discount = 44% of original price = 44% of $37 = 0.44 x 37 = $16.28
Sale price = $37 - $16.28 = $20.72
