Answer:
21 mails
Step-by-step explanation:
Let there are x no of texts and y no of emails.
Condition 1,
x+y = 20 ...(1)
Condition,
x=2y-1 ...(2)
Put the value of x from equation (2) in (1). So,
(2y-1)+y = 20
Taking like terms together,
2y-y=20+1
y=21
So, Devin sent 21 mails,.
Answer:
A) f(x) = 15x + 25; f(0) = 25
Step-by-step explanation:
x represents the amount of extra services, and 15x respresents the amount paid for all of the services. 25 represents the initial fee. f(0)=25 means that it cost $25 for a haircut with no extra services.
Let's say you have a haircut with two extra services. You would replace the x in the equation with the number of extra services, 2 in this case.
f(2)=15(2) + 25
f(2)=30+25
f(2)=55
It would cost $55 for a haircut with 2 extra services.
