Target sells 24 bottles of water for $3, and 36 bottles of water for $4. Which is the better buy and by how much?
1 answer:
Answer:
D) 36 bottles for $4 by 1.4¢ per bottle
Step-by-step explanation:
We calculate bottle per dollar for each option.
#A
Bottles/Dollar= bottles/dollar
#Both B and C charges the same as A and will have bottle/dollar ration of 8:1
#D
Hence, D is the better buy as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.

Point slope form is:
y -
= m(x - 
)
With and being the coordinate points, and m being the slope.
So the coordinate points are (4, -5), and the slope is -6 in this case.
So just substitute everything in, to get:
y - ( -5) = -6(x - 4)
Or
y + 5 = -6 (x - 4)
y -
With
So the coordinate points are (4, -5), and the slope is -6 in this case.
So just substitute everything in, to get:
y - ( -5) = -6(x - 4)
Or
y + 5 = -6 (x - 4)
Answer:
6 mph
Step-by-step explanation:
Use formula
where
D = distance
r = rate
t = time
In your case,
D = 12 mi
<u>Dina:</u>
D = 12 mi
r = 8 mph
t = ?
So,
<u>Masha:</u>
D = 12 - 3 = 8 mi
r = ?
t = 1.5 hours
