Looking at the permutation formula, we have n!/(n-r)!. n is the number of objects to select from and r is how many are to be picked at once. And 1 means multiply from there down basically. 5!/(5-4)!= 5*4*3*2*1/1. 5 times 4 is 20 times 3 is 60 times 2 is 120 times 1 is 1 so 120/1 is 120. There are 120 total combinations to be made from P, Q, R, S and T.
Price for jumbo size smoothie is $8.8. It is calculate by finding the price charged per ounce of smoothie and then multiplying it by the number of ounces.
Step-by-step explanation:
To find out the price of the 22-ounce smoothie, you will calculate the price per ounce of smoothie
<em>Ounce : Price</em>
12 : $4.8
1 : x
<em>Cross multiply</em>
12x = 4.8
x =
x = $0.4
So, 1 ounce costs $0.4,
22 ounces would cost---> 22 x 0.4 = $8.8
To check whether the small and large smoothies are priced in the same way,
1 ounce = $ 0.4
12 ounces = 0.4 x 12 = $4.8
16 ounces = 0.4 x 16 = $6.4
Therefore, the appropriate price for the jumbo size 22-ounce smoothie is $8.8 and the small and large smoothies are also priced in the same way.
