According to the graph, what is the value of the constant in the equation below?

D . 0.4

Step-by-step explanation:

let the height be the y coordinate

let the width be the x coordinate

first point :

width/x : 0.5

height/y : 0.8

according to the formula given:

height = constant/width :

so:

0.8 = constant/0.5

constant = 0.4

next point:

x : 0.8

y : 0.5

0.5 = constant/0.8

constant = 0.4

for all of the points, the constant is 0.4

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
