PLEASE HELP The ratio of boots to sandals in a shoe store is 8:3. If there are 245 more boots that sandals in the store, how many boots are there?

Answers

x - the number of boots
y - the number of sandals

The ratio of boots to sandals is 8:3.
$(x)/(y)=(8)/(3) \n8y=3x \ny=(3)/(8)x$

There are 245 more boots than sandals.
$y+245=x \ny=x-245 \n \ny=y \n(3)/(8)x=x-245 \n(3)/(8)x-x=-245 \n(3)/(8)x-(8)/(8)x=-245 \n-(5)/(8)x=-245 \nx=-245 * (-(8)/(5)) \nx=49 * 8 \nx=392$

There are 392 boots.
