a) write this as a formula with n representing the number of phone sold, and p representing the amount of money earned each week.

b) if 20 phones are sold the next week, how much money does Brian earn that week?

Answer 1

Answer:

n=30p=450

Step-by-step explanation:

10n+250=p

10×20+250=450

n=20 p=450

Answer 2

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
