On Monday Angela ate some grapes, Tuesday she ate 6 more than the day before. Each day of the week she ate 6 more than the day before. She finished off her grapes on Friday she had eaten 100.

How many grapes did she eat on Monday?

Step-by-step explanation:

You have to use this equation, we don't know how much she ate Monday so that is x, or really any letter. 6 to the seventh power is, 6•6•6•6•6•6, so multiply that and add 6 to the product until you get 10, and find out how many extra 6's you added to the product.
