Number of fake dollar offer to the student= [tex]Fake\ dollar\ offered\ for\ each\ perfect\ score\ \times\ number\ of\ maths\ test\ with\ perfect\ score[/tex]∴ Number of fake dollar offered to the student= [tex]5\times 4= 20\ fake\ dollar[/tex]
We know, student already have 25 fake dollar.
Next, finding total number of fake dollar student have.
Total fake dollar student have= [tex]fake\ dollar\ offered\ by\ teacher + fake\ dollar\ student\ already\ have[/tex].
Total fake dollar student have= [tex]20+25= 45\ fake\ dollar[/tex]
Hence, student have total 45 fake dollar to spend in the class store.
