For this case, the first thing we must do is define a variable.
We have then:
x: total sales for the week
We now write the equation that models the problem.
We have then:
p (x) = 0.035x + 300
Answer:
a function, p (x), which can be used to determine his pay for the week is:
p (x) = 0.035x + 300
3/4 times 60 = 45
45 mph is the answer
Put this sign in the blank >
we will have to buy 12.
<h3>How to solve?</h3>
We know to begin with that for x candy bards:
x / 10 = 0.89; x = 8.90
We are trying to ascertain how many bars (y) must be added to this to amount to have an average of 0.80. This is represented:
(8.9 + 0.72y) / (10 + y) = 0.8
8.9 + 0.72y = 0.8 (10 + y)
8.9 + 0.72y = 8 + 0.8y
8.9 – 8 = 0.8y - 0.72y
0.9 = 0.08y
y = 0.9 / 0.08 = 11.25
However, since we cannot have a partial amount of candy bars, we will have to buy 12.
