Answer:
10
Step-by-step explanation:
We can write Bailey's equation as:
29 + 1.50x
and Riley's equation as:
20 + 2x
Where
x is the number of magazines sold
Since Riley sold 12, her total pay for that day would be:
20 + 2x
20 + 2(12)
20 + 24
$44
Now, how many magazines Bailey need to sell? We equate Bailey's equation to 44 and find x:
29 + 1.5x = 44
1.5x = 44 - 29
1.5x = 15
x = 15/1.5
x = 10
hence, Bailey need to sell 10 magazines to make same money as Riley
