Answer:n=30p=450

Step-by-step explanation:10n+250=p

10×20+250=450

n=20 p=450

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) = 20 , so replacing the value ofin the formula we get :-

nn=》p = 10n + 250

=》p = ( 10 × 20 ) + 250

=》p = 200 + 250

=》p = $ 450

so, his total income in that week is

$450
