Question

a binder cost $7and each notebook cost $0.50 . you spent a total of $10.50

Answer 1

Answer:

Cost of a binder =$ 7

Cost of each notebook = $ 0.50

Total money spent = $ 10.50

Let the number of notebook be x ,

So,

no.of notebook = $ 0.5x

According To Problem,

$ 0.5x +7 = $ 10.5

=) $ 0.5x = $ 10.5 - 7

=) x = ( 3.5 ÷ 0.5 )

=) x = 7

Verification,

As,

$ 0.5x = $ 0.5 × 7

= $ 3.5

$ 3.5 + $ 7 = $ 10.5

Hope you get my answer correctly
