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 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
