Gracen went out to lunch. Her soda was $125, her hamburger (with cheese) cost $4.75, and she had apple pie for dessert that cost $2.50. She wants to leave a tip of 15%. How much should she leave?

She would leave a tip of $1.28

Step-by-step explanation:

So first if we add all of the expenses together we get $8.50. So her who lunch was $8.50. If she wants to leave a 15% tip, it would be 15% of her total cost so, 15% of $8.50 is 1.275. Rounded that's $1.28. She would leave $1.28 tip.

The probability will be number of Yellows divided by the total number of Marbles

Here there are 3 yellows and 11 marbles in total

The probability is

3/11
