A function is any relation that has only one output for one input. for each y put into the function, you can get one and only one output
Answer:
$45 dinner = $9
$1 dinner = 45/9= 5
$60 dinner = 60/5=12
Hence he got $12 for a $60 dinner
Perimeter = sum of all the sides
let x = one side
longer side = x + 10
Perimeter = x + x + x + x + 10
62 = 4x + 10
4x = 52
x = 13
Longer side = 23
Area = (10+23)x2/10
= 6.6
