    Step-by-step explanation:

    as he earns $250 per week , which is fixed and $10 for every additional smartphone he sells, then

    a.) the required formula is :-

    =》p = $250 + $10n

    =》p = 10n + 250

    ( p represents total income in week, n represents number of smartphones sold. )

    b.) so, here we get total number of smartphones sold ( that is n ) = 20 , so replacing the value of n in the formula we get :-

    =》p = 10n + 250

    =》p = ( 10 × 20 ) + 250

    =》p = 200 + 250

    =》p = $ 450

    so, his total income in that week is $ 450
