Step-by-step explanation:
Given that Crystal sold b balloons, Aliya sold 2 more balloons than Crystal and Shamika sold twice as many balloons as Crystal then forming the expressions;
If Crystal sold b number of balloons then;
a) Number of balloons Aliya sold is 2 more than Crystal's .This means Aliya sold two more balloons added to what Crystal sold.mathematically, it will be = 2+b
b) Number of balloons Shamika sold is twice Crystal's.This means Shamika sold double the number of balloons Crystal sold.If Crystal sold b balloons, twice this number is =2b
c)Total number of balloons sold will be presented by the expression;
=b+2+b+2b=4b+2
The expression for total cost will be;
$2*(4b+2) =$900----------------------expression
d) solving the expression for total cost as
2(4b+2)=900
8b+4=900
8b=900-4
8b=896 -------divide both sides by 8 to get b
b=896/8 =112 balloons ----------value of variable b
e)
Crystal sold b balloons = 112 balloons
Shamika sold, 2b, =2*112 = 224 balloons
Aliya sold , 2+b balloons = 2+112 =114 balloons
f)By solving the expression for total cost , you obtain the value of variable b which represents the number of balloons sold by Crystal. Using the value of b, you can calculate the number of balloons for Shamika and Aliya using their expressions which represent number of balloons they sold.
