1320

Step-by-step explanation:

Given: In pizza parlor, Number of types of crust = 4

Number of types of different toppings = 12

Number of types of cheese blends = 3

Now, the number of ways to choose a pizza with one type of crust, three different toppings, and one cheese blend

= $^{4}C_1\times\ ^{12}C_3\times\ ^3C_1$

= $4\times \ \dfrac{12!}{3!(12-3)!}\times 3\ \ \ \ [^nC_r=\dfrac{n!}{r!(n-r)!},\ ^nC_1=n]$

= $12\times\dfrac{12\times11\times10\times9!}{2\times6\times9!}$

= $12\times11\times10= 1320$

Hence, the required number of ways = 1320

30 cents

Step-by-step explanation:

2 dozen : $7.20

24 cookies : $7.20

/24 /24 (to find unit price)

1 cookie : 30 cents

btw it sounds like your using a math book. slader.com has a bunch of math books answer keys (i wasn't told to promote the btw)
