million less than twice the amount
pledged by Business B. If x represents
the amount pledged by the Business A,
write expressions to show the amounts

in terms of x.
b. The combined pledges of Business A,
Business B, and Business C totaled

Algebra Question 1  Reiny, Thursday, October 6, 2011 at 6:42pm
business A  x , x in millions
business B  2x  200
business C  2B  200 = 2(2x200)  200
x + 2x200 + 2(2x200)  200 = 1035
x +2x 200 + 4x  400 200 = 1035
7x = 1835
x = 262.143 million
Check:
A pledged 262.143 million
B pledged 324.286 million
C pledged 448.571 million
262.143+324.286+448.571 = 1035

business A=x
business B=2x20
business C=2x20+2(2x20)200
x+2x20+2(2x20)200=1035
x+2x20+4x40200=1035
7x=1035+20+40+200
7x=1295
x=185
Bus. A pledged $185 million
Bus. B pledged 185x2=37020=350 million
Bus. C pledged 350x2=700200=500million
185+350+500= $1035 million
