(12)(55)
(12)(54)
(11)($5
(11)(54)
save and exit

(11)($4)

Step-by-step explanation:

As total pounds of tomatoes = 11.2

Rounding off it becomes= 11

One pound cost = $4.19

Rounding off it becomes = $4

So the total estimated cost = (11)($4) = $44

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
