Kayla brought 80 packs of cat food to feed the cats outside. When the day was over, she had 30% less.
How much does Kayla have left?

It's 24 packs of cat food

Step-by-step explanation:

You have to think of it as 30% of 80.

30      ?

=

100    80

Now you have to find out what is in the blank by doing 80 times 30 to find what that equals. That equals 2,400. Now you have to find what times a 100 gets you 2,400. You divide a 100 by 2,400 to get 24. There's your answer

She had 24 packs left.

Step-by-step explanation:

The equation would be 24 * 30%. Since 30% is equal to 0.30, then we can write the equation as 24 * 0.30, which would equal 24!

Hope this helped!

Number of Small Cones Sold=22

Number of Large Cones Sold=34

Step-by-step explanation:

Suppose,

Number of Small Cones Sold: s

Number of Large Cones Sold: l

For the condition that, larges cones sold were 12 more than small ones, equation would be

and for the total revenue condition of $163

By solving equation (i) and (ii) simultaneously, we get

s=22

and

l=34

Hence, small cones sold would be 22 and large cones sold would be 34.
