Question

On a recent day 8 euros were worth 9 dollars and 32 euros were worth 36 dollars. Enter an equation of the form y = kx to show the relationship between the number of euros and the value in dollars. Let y be the value in dollars and x be the number of euros

Answer 1

Y=(9/8)x

Y= (36/32)x

Explanation:

. Let y be the value in dollars and x be the number of euros

We are told that On a recent day 8 euros were worth 9 dollars and 32 euros were worth 36 dollars.

Given equation of the form y = kx

Then k=y/x if we cross multiply

Then insert the values of

recent x= 8 euros were worth y= 9 euro

We have 9= k×8

Then K= 9/8

K=values of dollars/ number of Euro

If we input k into the eqn form y = kx

We have Y=(9/8)x

✓32 euros were worth 36 dollars

If we substitute into the form y = kx

We have 36= k×32

Then K= 36/32

Y= (36/32)x

Therefore, the relationship are ;

Y=(9/8)x

Y= (36/32)x
