Question

Find the hourly rate that the movers charge. What is the truck rental fee, shown as a point on the graph of the function for the total amount that Merrifield Movers charges

and what's the common difference of the arithmetic sequence

Answer 1

The common difference = 42

Explanation:

We are given the hourly rate that the truckers charge for moving things.

We are supposed to find the common difference of the sequence according to which the truckers charge money.

From graph, for 3 hours,the cost is 204 and for 6 hours it is 330.

Only the cost for first hour is different and for the remaining hours its the same.

Common difference =
`(330-204)/(6-3)`

= 42

Also for the first hour, the cost = x + 2
`*` 44 = 204

x = 116

The arithmetic sequence = 116 + 42n
