Answer:
Step-by-step explanation:
Let "a" and "m" represent the cost of an apple and a mango, respectively. Then Cameron's purchase can be represented as ...
4a +7m = 17.75
Gavin's purchase can be represented as ...
2a +5m = 10.75
Subtracting the first equation from twice the second gives ...
2(2a +5m) -(4a +7m) = 2(10.75) -(17.75)
3m = 3.75
m = 1.25
Then the price of an apple can be found from the second equation:
2a +5(1.25) = 10.75
2a = 4.50 . . . . . . . . . . subtract 6.25
a = 2.25 . . . . . . . . . . . divide by 2
The price of an apple was $2.25; the price of a mango was $1.25.
Add all the like terms
3b + b = b(3 + 1) = 4b
So, 3b + b + 6 = 4b + 6

Answer: 5:8, .625, 62.5%
Step-by-step explanation:
5 to 8 is already a ratio. Then all you have to do is divide it. Then to get the percentage, move the decimal point over to the right 2 places.
Let, the Total students = x
It would be: x * 35% = 105
x * 0.35 = 105
x = 105 / 0.35
x = 300
Now, 20% would be: 300 * 0.20 = 60 students
In short, Your Answer would be Option B
Hope this helps!
