Question

Which graph shows the equation c = 10+ 3t, where c is the total cost of going to the carnival and t is the number of $3 tickets purchased? Mark this and return

Answer 1

we have

$c = 10+ 3t$

where

c---------> is the total cost of going to the carnival

t---------> is the number of $\ 3$ tickets purchased

we know that

the domain of the function is the interval---------------> [0,∞)

Because the number of tickets can not be negative

The range of the function is the interval-------------> [10,∞)

Because the total cost can not be negative

using a graph tool

see the attached figure

Answer 2

There is nothing to mark...
The Graph would be a straight line and it increases. At the Point t=0 the graph has the value 10
