Criag is making making a model of his neighborhood that uses model trains. the ratio of the model train to the actual train is 1: 64. his neighborhood covers an area of 200,740 square feet. what would the area of the model neighborhood be.

Let x = the area of his model.  Set up a proportion. 1 is to 64 as the area of his model is to the area of his neighborhood. The order of the objects in the proportion is important. 1:64::x:200,704. Notice that the first thing in the first ratio (1:64) is the small number. The first thing in the second ration (x:200,704) is the small number. The small numbers go with the model.  The bid numbers go with the neighborhood. Set up the proportion: 1/64 = x/200,704. The small numbers are the numerators, the big numbers are the denominators.  Lots of folks have trouble with proportions because they don't keep the numbers consistent. Solve for x 200,704/64 = x x = 3136 The model will have an area of 3,136 square feet. You can set up the proportion with the big numbers on top and you get the same result. 64 is to 1 as 200,704 is to the area of the model. 64:1::200,704:x 64/1 = 200,704/x Cross multiply to solve. 64x = 200,704 x = 200,704/64 x = 3136.

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

Step-by-step explanation:

Find how much money is spent per hotdog:

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.
