The multiplier of each account's value is 1.05³ = 1.157625.
The $750 in the club's account will grow to
$750×1.157625 = 868.22
and each member will get 1/3 of that amount, $289.
The $250 in Sheri's individual account will grow to
$250×1.157625 = $289.
Sheri, Kayla, and Kayla's two friends will all have the same amount as a result of their investments.
The following equations are solved in terms of x:
a) 2x - 3 = y
2x = y + 3
x = (1/2)y + 3/2
b) 2 + 2x - 1 = 4y
2x - 1 = 4y
2x = 4y + 1
x = 2y + 1/2
c) 2A + 4x + 3B = 10
4x = 10 - 2A - 3B
x = 5/2 - (1/2)A - (3/4)B
3x + 8 = -22
-8 -8
3x = -30
x = -30/3 = -10
Correct choice is 1).
A trapezoid would work perfectly.
