Final price of the backpack (not including tax) = $16.74
Given that
Initial cost of backpack = $24.80
First Discount = 25% off Initial Cost =$ = $ 6.2
So modified price = 24.80 - 6.2 = $18.6
Also Harold has a coupon with 10% on the modified price.
so we can write 10% of $18.6 = $ 1.86
so we can write the final price for the backpack = 18.6 - 1.86 = $16.74

Answer:
y = (1/3)x + 7
Step-by-step explanation:
The slope of a line perpendicular to the given line y = -3x - 2 would have to be the negative reciprocal of the slope of the given line:
or, in other words,
the negative reciprocal of -3. That would be +1/3.
Starting with the slope-intercept form of the equation of a straight line, we have:
y = mx + b.
We substitute the coordinates of the given point, (-9,4), and the slope +1/3:
4 = (1/3)(-9) + b.
This simplifies to
4 = -3 + b, from which it can be easily seen that b = 7.
The desired line is y = (1/3)x + 7.
4x-10y=-20 /*(-3)
6x-15y=-30 /*2
-12x+30y=60
12x-30y=-60

what are the unit rates for those two and one more question: which is the better gbuy
Answer: 1. 0.19125 dollars per ounce, 2. 0.16083 dollars per ounce.
Step-by-step explanation:
In first question, a 24 ounce box of cornflakes cost $4.59
Therefore, 24 ounce = 4.59 dollars
⇒ 1 ounch = dollars
⇒ 1 ounch = 0.19125 dollars
⇒ Price of 1 ounce box of cornflakes equals to 0.19125 dollars.
⇒Thus the unit rate price of cornflakes = 0.19125 dollars per ounce
In first question, a 24 ounce box of cornflakes cost $4.59
Therefore, 36 ounce = 5.79 dollars
⇒ 1 ounch = dollars
⇒ 1 ounch = 0.16083 dollars
⇒ Price of 1 ounce box of cornflakes equals to 0.16083 dollars.
⇒Thus the unit rate price of cornflakes = 0.16083 dollars per ounce
