HURRY !!! Farmer McHenry is going to sell his tomatoes at the farmer's market. It costs Farmer McHenry $2.50 in gas, $1 for the
Korolek [52]

Answer:

Step-by-step explanation:

The total cost that farmer McHenry assumes to sell his tomatoes at the farmer´s market includes: the gas, the stand and the price tags. The expression is the following:

Total cost = $2,50 + $1 + $0.50

Total cost = $4

Farmer McHenry's revenue depends on the number of tomatoes he sells:

Revenue (t)= Price* t

Revenue (t)= $0.50(t)

To know how many tomatoes, he must sell so that the cost equals his revenue, you must equal both expressions and then find t:

$4=$0.50 (t)

t= $4/$0.50

t= 8  

He must sell 8 tomatoes.

Svetach [21]

Answer:

Step-by-step explanation:

First what we must do is rewrite the table to find a solution:

0.25^x −0.75x+1

   64     3.25

   16     2.5

    4      1.75

    1      1

 0.25     0.25

 0.0625 −0.5  

 0.015625  −1.25

We see where the values of the function are the same:

x = 0 (1)

x = 1 (0.25)

answer:

x = 0

x = 1
