Answer:
£152.40
Step-by-step explanation:
If he made 80 cakes at a ratio of 3:2:5, then he made:
24 chocolate cakes
16 lemon cake
40 fruit cakes
He sold all of the chocolate: 24x2=48
He sold 3/4 of the lemon: 3/4 of 16=12 12x1.70=20.40
He sold 7/8 of the fruit cakes: 7/8 of 40=35 35x2.4=84
48+20.40+84=152.40
Answer:
The total number of ways are 30.
Step-by-step explanation:
Consider the provided information.
We need to write 3-letter "words" from the letters of "Adelphi" so that the first and last letters are vowels.
The number of letters in "Adelphi" = 7
The number of vowels are = 3
It is given that the first and last letters are vowels.
For first letter we have 3 choices, and for the last letter we have 2 choices as repetition is not allowed.
If we have selected first and last letter that means now we have 5 letters for the middle letter. (7-2=5)
So the number of possible choices for the 2nd letter is 5.
Hence, the total number of ways are: 3×5×2 = 30 ways
Answer:
10 days
Step-by-step explanation:
Jenny has read 50 pages and will read 15 each day.
The equation would be: 15x+50
Mark will read 20 pages daily.
The equation would be: 20x
In both equations x represents days.
You set both equal to each other because you want to know when they read the same amount of pages.
15x+50=20x
...you subtract 15x from both sides
50=5x
...and divide by five to get: 10 days
9/-5 ÷ -3/8 = 9/5 ÷ 3/8 = 27/8/5= [8•5=40] = 27/40
