Answer:

$1470

Step-by-step explanation:

sneakers : boots

15 : 19


15        cost sneakers

------ =  -------------------

19          570


using cross products

15 * 570 = 19 * sneakers

8550=19 * sneakers

divide by 19

8550/19 = sneakers

sneakers = 450

total cost = 2* sneakers + boot

total cost = 2 * 450 + 570

total cost = 900 + 570

total cost = 1470
