Answer:
£162.35.
Step-by-step explanation:
Total of letters + packages = 300.
Number of packages = 300 * 16 / ( 16+59)
= 300 * 16/75
= 64
So number of letters = 300 - 64 = 236.
No. of first class letters = 236 * 1/4 = 59.
No. of 2nd class letters = 236 - 59 = 177.
Total cost
= 64*1.2 + 0.52*59 + 0.31*177
= 162.35.
I actually don’t know... Sorry...
I checked I could do a fraction but my calculator won't allow
Answer:
3 1/3 gallons per minute
Step-by-step explanation:
We can use ratio's to solve this problem. We will put gallons on top and time on the bottom
5/6 gallons x gallons
-------------------- = -------------
1/4 minute 1 minute
Using cross products
5/6*1 = 1/4 x
Multiply by 4 on each side
5/6 * 4 = 1/4 *4 x
20/6 = x
Dividing the top and bottom by 2
10/3 =x
Changing this back to a mixed number
3 goes into 10 3 times with 1 left over
3 1/3 gallons per minute
