First, let's write this as an equation.

f(x)= price of an item

p= percent increase

f(x)=xp^2

1.44x=xp^2

1.44=p^2

\sqrt{ 1.44}= \sqrt{p^2

p=1.2

1.2=120%

Answer: The second price was a 120% of the first price which means that the second increase was 20% more than the first price.

Hope this helps!

Elliot is buying groceries. He buys a bag of apples for 5.54, a loaf of bread for 2.49, and a jar of peanut butter for 3.73. Ell
zloy xaker [14]

Answer:


Step-by-step explanation:

First, you want to add up the subtotal together, so its 5.54+2.49+3.73, and adding those together you get 11.76 as your subtotal. To figure out change, you simply subtract your subtotal to the amount he paid in. For that it is 20-11.76, and that is 8.24

Elliot gets $8.24 in change.

Hope this helps.

This question is too hard
OLga [1]

Answer:

27 children

Step-by-step explanation:

For every 9 children, there are 4 adults. Those numbers added together equal 13. Now, if we divide the total number of adults and children by 13, we will get the number of how many groups there are of 9 kids and 4 adults.

39 / 13 = 3

There are 3 groups of 9 kids and 4 adults, which means to find the total number of children, we have to multiply 3 by 9.

3 * 9 = 27

Therefore, there are 27 children total. I know this was probably really confusing, but I hope it helped in some way! Have a lovely day!! :)
