Explanation:

Hello , I think I can help you with this

you can solve this using a simple rule of three

Step 1

the cost of the dinner is the 100%

$ 15 = 20%

$x? =100%

the proportion is

`(15)/(20)=(x)/(100)`

Step 2

solve for x

`(15)/(20)=(x)/(100)\\x=(100*15)/(20)\\x=(1500)/(20)\\x=75`

the cost of the dinner is $75

Have a nice day.
