Answer:

x=   1 1/4 ounces

Step-by-step explanation:

We can use a proportion to solve this problem.  Put the cost over the number of ounces.


$4                  $1

5 ounces       x ounces

Using cross products

4x =1*5

Divide each side by 4

x =5/4

x=   1 1/4 ounces

5 divide by 4 is 1.25 which means that for 1$ you could buy 1.25 ounces

frozen [14]

Answer:

62.5%

6250/10000 x 100%

0.625 x 100%

62.5%

62.5% of the people at the concert are adults
