C/3-7=5.3 how do I do this?

The amount of hotdogs you would need to sell in order to reach $300= 80

Step-by-step explanation:

140÷70=2

$140= Amount made by selling 70 Hotdogs

70=Amount of Hotdogs sold already

Dividing 140 by 70 will get you the cost of 1 hotdog. This is due to division being the act of separating something into parts. There are 70 parts (or hotdogs) in this equation so therefore by separating the amount of money made by those selling those parts, the amount per hotdog would be found.

      2. Find the amount of hotdogs it would take to earn a total of $300:

300-140= 160  160÷2= 80

The question asks for a total of $300 to be earnt by selling hotdogs. $140 has already been earnt, therefore a portion of the total amount has been made. By subtracting the amount already made by the total amount of money that is wanted to be earnt, the amount of money needed to reach the $300 is found. The $160 is then divided by the amount of money spent per hotdog ($2). The answer (80) is the amount of hotdogs required to be sold to reach the goal of $300.
