Rita goes to the mall. If d is the number of items she bought, the expression 16.78d+23 gives the amount she spent in dollars at one store. Then she spent 26 dollars at another store. Find the expression which represents the amount Rita spent at the mall. Then estimate how much Rita spent if she bought 3 items.

The expression 16.78d + 49 represents the amount Rita spent at the mall.

If she bought 3 itens, Rita spent $99.34.

Step-by-step explanation:

Expression:

First store: 16.78d + 23

Second store: 26

Total: 16.78d + 23 + 26 = 16.78d + 49

Then estimate how much Rita spent if she bought 3 items.

Now, we have that d = 3. So

16.78*3 + 49 = 99.34

If she bought 3 itens, Rita spent $99.34.
