Answer: $0.3 per lb per year.

Step-by-step explanation:

We know that the rate of change in price is given by :-

$r=\frac{\text{Change in price}}{\text{Time}}$

Given: The price of apples went from $1.99 per lb to $3.19 per lb in four years.

Change in price = $\$3.19-\$1.99=\$1.2$

Time = 4 years

Now, the rate of change of the price of apples is given by :-

$r=\frac{1.2}{4}=0.3$

Hence, the rate of change of the price of apples= $0.3 per lb per year.

-12=15c+3/6 what is the answer

erik [133]

First, I would switch the sides of the equation around.

15c + 3/6 = -12

Then, simplify the equation.

15c + 1/2 = -12

Now, we need to get 15c alone since it carries the variable. We can do this by canceling 1/2 out by subtracting 1/2. Remember what you do to one side you must do to the other.

15c +1/2 = -12
-1/2 -1/2
↓
15c = -12.5

Next, get c by itself by dividing both sides by 15, because what you do to one side you must do to the other .

15c ÷ 15 = -12.5 ÷ 15
↓
c = -5/6
