Although the problem above may look really different or much harder than any equation we have solved before, guess what?! It's not! We still use the same properties to solve these kinds of equations. On the left side of the equation you have a fraction with a numerator of (4+8) ( 4 b + 8 ) and a denominator of (2) ( 2 ) . The variable is in the numerator of the fraction so we will need to get rid of the denominator first. The numerator is being DIVIDED by the denominator so how do we undo division? We multiply! Multiply both sides by the denominator, 2 2 , and simplify. (2)4+82=10(2) ( 2 ) 4 b + 8 2 = 10 ( 2 ) 4+8= 4 b + 8 = Now we have a simple two-step equation. Subtract 8 8 from both sides. 4= 4 b = Lastly, divide both sides by 4 4 to isolate the variable. = b =

a) 40 more; b) old factory:   10%, new factory:   16%; c) week 4

explanation:

a) at week 0, we see in the graph that the new factory produces 190 specialty items.  

using the function, substituting 0 in for w,

this is a difference of 230-190 = 40.

b) the function for the old factory is written in the form f(x) = a(1+r)ˣ, where a is the original amount, x is the amount of time and r is the growth rate.   the equation for the old factory is ; 230 is in place of a and is the original amount; w is the amount of time; which means 1+r = 1.1.   this means that r must be 0.1 or 10%.

for the new factory, we find the percent of increase to find the growth rate; the formula for this is

between the first two points, the amount of change is 220-190 = 30; this gives us

30/190 = 0.158 ≈ 0.16 = 16%

c) at week 0, the old factory has 230 while the new factory has 190.

at week 1, the old factory has 230(1.1) = 253 while the new factory has 220.

at week 2, the old factory has 230(1.1²) = 278.3 while the new factory has 252.

at week 3, the old factory has 230(1.1³) = 306.13 while the new factory has 290.

at week 4, the old factory has 230(1.1⁴) = 336.743 while the new factory has 337.   this is the first week that the new factory surpasses the old.
