Answer:

C. the probability of it not happening is 0.3.

Answer:

D)$42.00

Step-by-step explanation:

18 3/4 is equal to 18.75, so 18.75x2.80 is your original cost (52.5). After doing that, since 52.5=100% you are going to divide 52.5 by 5 since 20x5=100. So 20% is 10.5. 52.5-10.5= $42.00

Mama L [17]

By taking a subtraction, we will see that the change that Kate receives is $1.08

<h3></h3><h3>How to get the change?</h3>

The change will be given by the difference between what Kate has, and the cost of all the items she buys.

She has $20.00, and the costs are: $6.99, $3.98, and $7.95.

Then the change will be:

C = $20.00 - $6.99 - $3.98 - $7.95 = $1.08

We conclude that the change is $1.08
