Question

Jane saved $800. Her sister has 10 times as much money. How much money does jane's sister have?

Answer 1

Jane's money $800
Her sister has 10 times more money then Jane.

So the way to solve this should be

X(Jane's Sister Money) = 800 * 10 ⇒ X = 8000$

I hope you understood.

Answer 2

Because her sister has 10 times as much money, just do $800 times 10, which is $8,000
