Answer 1

Adelaide will have $51.01 left after she puts 10% in her piggy bank and buys all the items she wants.

Step-by-step explanation:

In order to find out how much money Adelaide will have left, we need to calculate the total cost of the items she wants to buy and the amount she needs to put in her piggy bank. First, let's calculate the total cost of the items:

1. Jeans: $49.00
2. Necklace: $19.99
3. T-shirts: 2 x $7.50 = $15.00

The total cost of the items Adelaide wants to buy is $49.00 + $19.99 + $15.00 = $83.99

Next, let's calculate the amount Adelaide needs to put in her piggy bank:

10% of $150.00 = $15.00

Now, we can calculate how much money Adelaide will have left:

Total earnings - Total cost of items - Amount in piggy bank = $150.00 - $83.99 - $15.00 = $51.01

Therefore, Adelaide will have $51.01 left after she puts 10% in her piggy bank and buys all the items she wants.
