Answer:
Red grapefruit costs more per pound.
Step-by-step explanation:
Red grapefruit
y =2x
This is in the form y= mx+b where m is the slope and b is the y intercept
The cost per pound is the slope, which is 2
The cost per pound is $2
Pink grapefruit
We need to find the slope
We have 2 points (0,0) and (4,4)
m = (y2-y1)/(x2-x1)
= (4-0)/(4-0)
=4/4
= 1
The slope is 1
The cost per pound is $1
Answer:
V = (1/3)pi(r^2)h (the first one)
X is amount of books.
x ≤ 9 if the books are 2 inches thick.
x ≤ 18 if the books are 1 inches thick.
Equation for 1 inches.
x ≤ 18
Equation for 2 inches.
2x ≤ 18
Equation for both.
x + 2y = 18
y is amount of 2 inch books
This one equation above is standard form.
Remember 800 because that’s your big number / most important.
So they’re open from 8am - 10pm. They’re open for 14 hours a day and they sell 16 rolls per hour.
If one hour is 16 rolls sold , then what is 14?
16 x 14 hours (16 x 14 = 224)
In a whole day they sell 224 rolls.
Monday: 800 rolls - 224 rolls = 576 rolls
Tuesday: 576 rolls - 224 rolls = 352 rolls
Wednesday: 352 rolls - 224 rolls = 128
By Thursday they won’t be able to sell more than 224 because there is only 128 rolls left that will be sold out in 8 hours on that day.
So they will be sold out completely by THURSDAY.
The best time to go to the store is most likely on a Tuesday around 12-1pm
