Given:
The cost price=$700.
The selling price =$1000
Required:
We need to find the markup and markup rate.
Step-by-step explanation:
Consider the markup formula.
![Markup=Selling\text{ price-cost price}](https://img.qammunity.org/2023/formulas/mathematics/college/glgv48h1zvb2xl1kv3xcq7z7o5bvqmgxrd.png)
Substitute Selling price=1000 and cost price =700 in the formula.
![Markup=1000-700](https://img.qammunity.org/2023/formulas/mathematics/college/cbiku4cxzqaz2ov8l69evgphxdj0pazg7s.png)
![Markup=\text{ \$}300](https://img.qammunity.org/2023/formulas/mathematics/college/aaii42ca817e3235309hpym44prdjwagzo.png)
Consider the markup rate formula.
![Markup\text{ rate}=\frac{Sellingprice-costprice}{cost\text{ price}}*100](https://img.qammunity.org/2023/formulas/mathematics/college/jznj362nxnb1mxp9fga2mtbx6b75c3dx6m.png)
Substitute Selling price=1000 and cost price =700 in the formula.
![Markup\text{ rate}=(1000-700)/(700)*100](https://img.qammunity.org/2023/formulas/mathematics/college/bkkzrbedtvuzrvww2z4hvb296od3fciwgz.png)
![Markup\text{ rate}=(300)/(700)*100](https://img.qammunity.org/2023/formulas/mathematics/college/4j4zaadnn92o5rhtx71v548ioic8xo0fuq.png)
![Markup\text{ rate}=42.85714](https://img.qammunity.org/2023/formulas/mathematics/college/h4u34mbcl8pb5ay6t4qqgsz5itr9ycpm2o.png)
![Markup\text{ rate}=42.86\text{ \%}](https://img.qammunity.org/2023/formulas/mathematics/college/vaobekn1ccczpszyqxiv98hhi0pwedk9ud.png)
Final answer:
![Markup\text{ in dollars}=\text{ \$}300](https://img.qammunity.org/2023/formulas/mathematics/college/6jtsnnqvk7ojx1j0hisr4joqn2lcmson5c.png)
![Markup\text{ rate}=42.86\text{ \%}](https://img.qammunity.org/2023/formulas/mathematics/college/vaobekn1ccczpszyqxiv98hhi0pwedk9ud.png)
