Find the unit rate with the second given unit in the denominator.
$67.50 for 9 pizzas
a.$15/pizza
b.7.50pizza/$
c.15pizza/$
worth 8
d.$7.50/pizza

To find unit rate:
divide the top number by the bottom number

the fraction in this problem is 67.50/9
so you divide 67.50 ÷ 9 = 7.5
since the unit rate we are looking for happens to be money, you have to have 2 digits after the decimal, so add a zero to make 7.5 into $7.50

It is $7.50 per pizza, so the correct answer is D.
