Answer:
Answer (a):
distance traveled per revolution = 1.5 feet
Answer (b):
slope = 1.5 feet per revolution
Step-by-step explanation:
We have been given a graph which shows number of revolutions v/s distance traveled in feet.
Answer (a):
Now we need to find about how far does Miguel travel per revolution. That means find distance traveled in 1 revolution.
From graph we see that 10 revolution corresponds to 15 feet.
then 1 revolution = 15/10 = 1.5 feet
hence final answer is 1.5 feet.
Answer (b):
slope means [change in y-value] / [change in x-value]
From graph we see that 10 revolution corresponds to 15 feet.
then slope = 15/10 = 1.5 feet per revolution
Here, we need to construct 2 linear equation.
Let x be the plate and y be the cup.
1) 4x + 3y = 20.70
2) 5x + 4y = 26.40
From equation 1, we solve for y.
3y = 20.70 - 4x
y = (20.70 - 4x) / 3
Substitute into equation 2.
5x + 4((20.70 - 4x) / 3) = 26.40
5x + 27.60 - 5.33x = 26.40
-0.33x = 26.40 - 27.60
-0.33x = -1.2
x = 3.64
We already get value of x. Now, calculate for value of y.
y = (20.70 - 4x) / 3
y = (20.70 - 4(3.64)) / 3
y = 2.05
The cost for 1 plate is 3.64 dollars and 1 cup is 2.05 dollars.
You take the discount first. Alex is completely right. Laura is if and only if that 110% is really just 10%. So I'll use Alex's method because it is for certain correct.
28.5*35/100 = 9.975 (which is the amount of the discount)
28.5 - 9.975 = 18.525 (which is the amount paid with the discount factored in.)
Now you take 10% of this amount and add it on which gives 18.525 * 10/100=1.825 which is the amount of the tax.
Add this on to the selling price 18.525 + 1.825 = 20.3775 and now is the time to do your rounding.
The cash register will ring up 20.38 which is just under $21.00
Answer: $20.38
