Answer:

6 slices

Step-by-step explanation:

The full pizza is 12 pieces.  Divide 12 by 4 to find out how much she ate on Thursday.   1/4 of 12 is 3 so she ate 3 slices on Thursday.  Subtract 3 from 12 to find out how much was left for the next day.  There were 9 slices the next day.  Next, divide 9 by 3 to find out what 1/3 of 9 is.  1/3 of 9 is 3 so subtract 3 from the 9 slices.  6 slices are the original pizza remain.

Comment
You need to set up a direct proportion. You have to relate Keith and Jared's ages to the ratio you were given.

Givens
Keith is 24
Keith / Jared = 3/5
J = Jared 

Solution
3/5 = 24 / J Cross multiply
3*J = 5 * 24 Combine factors on the right.
3J = 120     Divide by 3
J = 120 / 3
J = 40

Conclusion
Jared is 40 years old.

Tito receives a weekly salary of ​$450 at an appliance store. He also receives a 4 percent commission on the total dollar amount
Kay [80]
<h2>Hello!</h2>

The answer is:

Tito needs a total of $6500 in sales if he want to receive $710 a week.

The equation is:

TotalAmount=450+Sales*0.04

<h2>Why?</h2>

From the statement we know that his salary is $450 plus a 4% commission on the total amount of all sales he makes.

So, we can write the following equation to determine the total sales in a week if he wants to make a total of $710.

Remember, if we are working with percents, we need to change it to real numbers in order to perform the calculations, we can do it by dividing the percent value into 100.

We have:

TotalAmount=450+Sales*0.04

Now, if he wants to make a total of $710, we have:

750=450+Sales*0.04

750-450=Sales*0.04

Sales=\frac{710-450}{0.04}=6500

We have that Tito needs a total of $6500 in sales if he want to receive $710 a week.

Have a nice day!
