Ninety-three percent of a town’s population own cars. If the number of cars owned is 5,208, what is the population of the town, if nobody owns more than 1 car?PLEASE HELP, I DON'T GET THIS!! :((

Answers

Hey there :)

93% of a town's population own cars
If number of cars owned is 5,208

Population of town is?
Let p represent population of town

(93)/(100) of p = 5208
(93)/(100) × p = 5208

Divide 5208 by p in order to do cross multiplication ( easier way )
(93)/(100)= (5208)/(p)

Cross multiply:

93p = 5208 × 100
93p = 520800

Divide by 93 in order to find value of p
(93p)/(93) = (520800)/(93)
p = 5600

The total population of the town is 5600



What the problem is saying is that 93% of the town's population is 5,208. If no one owns more than one car, then each car in the town accounts for one person. So, therefore, 93% of the town = 5,208.

The total population of the town can be found by setting up a proportion.

(5208)/(93) = (x)/(100)

Cross-multiply: 520800=93x

Solve for x, the town's population: x=5600

There are 5,600 people in the town.

kenny has 9 more comic books than bobbie. together they have 95 comic books. define a variable. then write an equation that could be used to find the number of comic books they each have.

Answers

Number of comic books Bobbie has - b

95 = (9 + b) + b

Since 95 is the total number of comic books both boys have, it is equal to both boys' books added together. However, since we don't know how many books Kenny has, and only that he has 9 more than Bobbie, we can define that as (9 + b), or nine more than b. Then, we add b again, because (9 + b) is the number of books Kenny has, and if we add that to the number of books Bobbie has, it will equal the total of 95 comic books.
