Helen wants to buy a dictionary that costs $7, a dinosaur book that costs $16, and a children's cookbook that costs $17. She has saved $25 from her allowance. How much more money does Helen need to buy all three books?

Respuesta :

Answer:

Helen requires 15$ more to buy the three books.

Step-by-step explanation:

We are given the following in the question:

Cost of dictionary = $7

Cost of dinosaur book = $16

Cost of cook book = $17

Helen's allowance = $25

Total cost of three books =

[tex]=7 +16+17\\=\$ 40[/tex]

Extra money required to buy three books =

[tex]=40-25\\=\$15[/tex]

Thus, Helen requires 15$ more to buy the three books.
