3 boxes of paper cost 3*21.99=65.97, 2 toner cartridges cost 2*52.90=105.8.
Given that there's 20% off for all office supplies, then 3 boxes of paper cost 3*$21.99*0.8=$52.78,
2 toner cartridges cost 2*$52.90*0.8=$84.64, the price of folder is $0.99*0.8=$0.792.
So, after buying these things given that there's 20% off for all office supplies, he will have only
$175-$52.78—$84.64= $37.58.
As 37.58/0.792=47.45, hence he can buy only 47 folders
Answer is 47
Answer:
The dog will catch the cat at 33.33 sec
Step-by-step explanation:
Let
x------> distance the cat runs before being caught by the dog,
Remember that
The speed is equal to divide the distance by the time
v=d/t
solve for t
t=d/v
so
equate the time
x/24=(200+x)/30
30x=24(200+x)
30x=4,800+24x
30x-24x=4,800
x=4,800/6=800 m
t=d/v=800/24=33.33 sec
or
t=(800+200)/30=1,000/30=33.33 sec
Answer:
Step-by-step explanation:
f(x) = 4x + 7

Answer:
9/10ths of a mile. Or 0.9 miles.
Step-by-step explanation:
To get the total it's helpful to look at it in decimals:
2/5 mile = 0.4 miles (1 mile divided by 5 = 0.2 miles, times that by 2)
1/2 mile = 0.5 miles
Add them together = 0.9 miles.
Which is 9/10ths of a mile.
