Xylia, Emily and Jaslyn each sold an equal number of cookies. Xylia collected a total of $74.10 from selling 9 mocha cookies and some mango cookies. Emily collected a total of $82.60 from selling 14 mocha cookies and some mango cookies. How much did Jaslyn collect if she sold only mango cookies?
Emily collected more money than Xylia from the sale of the cookies but the number of cookies sold by each girl was the same. This shows that each mocha muffin is higher priced than each mango muffin. 

Amount that Emily collected more than Xylia
= 82.60 - 74.10
= $8.50

Number of more mocha cookies that Emily sold
= 14 - 9
= 5

Extra amount collected from the sale of each mocha muffin
= 8.50 ÷ 5
= $1.70

Total extra amount collected from the sale of 9 mocha cookies
= 9 x 1.70
= $15.30

If Xylia sold only mango cookies, she would collect $15.30 less than her original amount.

Amount that Jaslyn collected if she sold only mango cookies
= 74.10 - 15.30
= $58.80

Answer(s): $58.80
