Answer:

Step-by-step explanation:

n(AUB)=n(A)+n(B)-n(A∩B)

greatest intersection of (A∩B)=65

n(A∪B)=80+65-65=80

so least value of n(A∪B)=80

there are two pizzas. Conor ate 1/4 of a pizza, Brandon ate 2/8, Tyler ate 3/4, and Audrey ate 4/8. who ate the most of the two

Let's say that each pizza is sliced into 8 equal sized pieces, I have to make all of the fraction have the denominator of 8.
Conor: 1/4 * 2/2 = 2/8
Tyler: 3/4 * 2/2 = 6/8
Brandon: 2/8
Audrey: 4/8
Then I'll put the fractions in order from least to greatest. 2/8, 2/8, 4/8, 6/8. Then you would have to multiply each fraction by 2 since there are two pizzas that have 8 equally sized pieces.
Brandon: 2/8 *2/2 = 4/16
Conor: 2/8 * 2/2 = 4/16
Audrey: 4/8 * 2/2 = 8/16
Tyler: 6/8 * 2/2= 12/16
This means that Tyler ate the most of the two pizzas.

I=PRT

$60= 400 ×.05 × t

$60= 20× t

t= 60/20
