We have 1, 3, 4 and 5

All are distinct numbers.

To form a two digit number, we have two places to fill with digits: _ _

The first place can be filled in 4 ways.

The second place can also be filled in 4 ways as repetation is allowed.

So total number of ways = 4×4 = 16

You can form 16 two digit numbers.

Part A) First, you need to find out how much she makes each hour.40/5 = 8 & 48/6 = 8 ... This shows that she makes $8 an hour 

To find the first missing number, you will do 8 * 8 = 64 ... This shows that she makes $64 in 8 hours.

To find the second missing number, you will do 56/8 = 7 ... This shows that she makes $56 in 7 hours.

Part B) Barb makes $9 every hour. To find the amount of money she earns for 5, 6, and 8 hours of work you will need to multiply $9 by the amount of hours she worked.

9 * 5 = 45 ... This shows that she makes $45 in 5 hours.

9 * 6 = 54 ... This shows that she makes $54 in 6 hours.

9 * 8 = 72 ... This shows that she makes $72 in 8 hours.

Part C) In part B, you found out how much she makes after working at the theme park for 5 hours. ($45 in 5 hours)

Next, you'll need to find out how much she makes after mowing lawns for 5 hours.
5*8 = $40 ... This shows that she makes $40 in 8 hours

Now you need to the difference. 45 - 40 = 5 ... She makes 5 more dollars working at the theme park for 5 hours than mowing lawns for 5 hours.
