Question

Margos dad offers to give her 5 cents on Sunday.Then for each day of the week, he offers to give her 5 times the amount from the previous day. How much will he give her on Saturday? Write an expression to show how much margos das gives her on Saturday

Answer 1

5⁽ⁿ⁺¹⁾

Explanation:

Margo's dad gives her 5 cents on Sunday.

Then he gives her 5 times the amount from the previous day, till Saturday.

Forming an expression in order to calculate the amount of money Margo's dad gives her on Saturday,

We get 5⁽ⁿ⁺¹⁾ ,

Where n = number of days after Sunday

After Sunday there are 6 days till Saturday.

Therefore, the amount received by Margo = 5⁽⁶⁺¹⁾ = 5⁷

= 78,125 cents

Answer 2

The equation or expression that we can generate from the problem is a power equation in the form of:

5^(x+1)

where x is the the number of days that have passed

From Sunday to Saturday 6 days have elapsed, therefore:

5^(6+1) = 78,125

Therefore Margos should receive 78,125 cents on Saturday.
