I think it would be C because the equation is y=7x. y=7x is also equal to x=1/7y. If y=45.50, then you would have to divide y by 7, which would equal 6.5.

The recipe makes enough stew for 6 people, and the ingredients cost $9.75. How much would it cost to serve 24 people?

Leno4ka [110]

If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as

6 people - $9.75,

24 people - $x.

Or as proportion,

$\dfrac{6}{24}=\dfrac{9.75}{x}.$

Find x:

$6\cdot x=9.75\cdot 24,\\ \\x=\dfrac{9.75\cdot 24}{6}=9.75\cdot 4=39.$

Answer: It would cost $39 to serve 24 people
