Answer:

60 push-ups

Step-by-step explanation:

Set up a ratio to represent the problem:

Molly : Liza

10 : 15

40 : ?

How did we get from 10 to 40?

You multiply by 4. Therefore, multiply by 4 on both sides of the ratio.

10 : 15

x4   x4

40 : 60

So, Liza does 60 push-ups while Molly does 40.

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W
Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2         46.5

5         116. 25

7         162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

2 \; \rm Jackets =\$ 46.50

1 \;\rm Jacket = \dfrac {\$46.50}{2}

1 \;\rm Jacket = \$ 23.25

Now the cost price of 3 jackets is given as,

3\;\rm Jackets = \$23.25 \times 3

3\;\rm Jackets = \$69.75

Hence we can conclude that the cost price of 3 jackets is $69.75.

To know more about the cost price, follow the link given below.
