Question

The price of tomatoes at a farm is $0.54 per pound. Which equation can be used to determine c, the total price of n pounds of tomatoes?
c = 0.54n
c = 0.54 over n
c = 0.54 + n
c = 0.54 − n

Answer 1

is it a?

Answer 2

c=54n

Answer 3

u sure

Answer 4

yes

Answer 5

The graph below shows the prices of different numbers of boots at a store:

A graph is shown. The values on the x axis are 0, 2, 4, 6, 8, and 10. The values on the y axis are 0, 25, 50, 75, 100, and 125. Points are shown on ordered pairs 0, 0 and 2, 25 and 4, 50 and 6, 75 and 8, 100. These points are connected by a line. The label on the x axis is Number of Boots. The title on the y axis is Price in dollars.

Which equation can be used to determine p, the cost of b boots?
p = 12.50b
p = 25b
b = 25p
b = 12.50p

Answer 6

a line in slope-intercept form is
y= mx + b
the x is along the x-axis (sideways)
and the y is vertical axis (up/down)

in your problem they say boots is on the sideways axis

so should you expect
p= m*b
or
b= m*p
?
any idea ?

Answer 7

i think b= m*p

Answer 8

sorry i mean p= m*b right?

Answer 9

yes p= m*b because b (for boots I assume) is "sideways" along the x-axis

m is the slope. change in y divided by change in x
or in this case change in p divided by change in b
can you find the slope ?

ok thx :D
