A mattress store is having a sale. All mattresses are 30% off. Nate wants to know the sale price of a mattress that is regularly $1,000.

$700

Step-by-step explanation:

if you do the problem up like this,

you have to cross multiply,

30x1000= 30000

then divide

30000/100 = 300

since the discount is $300 off for a $1000 dollar mattress, you just need to subtract $300 from $1000.

1000-300=700

thats how you get $700!
