Lorico [155]
Let width = x ft  then 
2x + 2(2x) = 42
6x = 42
x = 7 

so the width is 7 ft and length is 14 ft.

So the cost to build the pen =  14*1.25 + 14*1,25 + 7*2.50 + 7*2.50

A store allows customers to fill their own bags of candy. Terri decides she only wants jelly beans and chocolate drops. Jelly be
NISA [10]
Jelly beans - $0.98 per pound
chocolate drops - $0.67 per pounds
Terri's bag = 2.1 pounds and $1.56

p = represents the pounds jelly beans.
c = represents the pounds in chocolate drops

p + c  = 2.1
0.98p + 0.67c = 1.56

c = 2.1 - p  ; number of pounds of chocolate drops

0.98p + 0.67(2.1 - p) = 1.56
0.98p + 1.41 - 0.67p = 1.56
0.98p - 0.67p = 1.56 - 1.41
0.31p = 0.15
p = 0.15/0.31
p = 0.48 pounds of jelly beans

c = 2.1 - 0.48
c = 1.62 pounds of chocolate drops.
