The average price of a gallon of orange juice from october 2013 to september 2014 can be modeled by the function f shown, where x represents the number if months since october 2013,
f(x)=6.12+0.03x
complete the sentence to describe the change in average price of a gallon of orange juice from october 2013 to september 2014
the average price of a gallon of orange ( 1st-blank) by (2nd-blank) each month
1st -decreased or increased
2nd- 3% or 612% or $0.03 or $6.12

The average price of a gallon of orange increased by $0.03 each month.

Step-by-step explanation:

It is 11 months between October 2013 and September 2014 so the price after 11 months =

f(11) = 6.12 + 0.03(11)

= 6.12 + 0.33

= $6.45.

This is an increase of 0.33 / 11 = 0.03 / month.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
