Answer:
398-cent stamp for postage.
Step-by-step explanation:
For one letter, Travis needs 37-cent stamp
For four letters, Travis needs 37-cent stamp x 4 letters
= 148-cent
Again,
For one postcard, he needs 25-cent stamp
For ten postcards, he needs 25-cent stamp x 10 postcards
= 250-cent
Therefore, he will spend = (148-cent + 250-cent) = 398-cent stamp for postage.

Answer:
7x-48
Step-by-step explanation:
we want our equation to look something like this
y=mx+b
let's start by solving for m (the slope) using the slope formula

Which means, so far, our equation looks like this
y=7x+b
now we just need to solve for B
We can do this by plugging in a set of coordinates
-6=7*6+b
-6=42+b
-48=b
which means our equation is
7x-48
