Question

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y=kx to show the between the number of euros and the value in dollars. Sentence: ___________, where y is dollars and x is euros.

Answer 1

$9= k•8 euros so k=9/8=1.125
So for every 1 euro we have $1.125
y=1.125•x

$27=k•24 euros so k=28/24=1.166666667
y=1.67•x
