10% is $8.00 so 20% is $16 and 80-16= 64 so the sale cost is $64.00
First add up the total parts in the ratio.
5 + 4 = 9
Now we need to know the value of each part
36 / 9 = 4
The girls has total of 4 parts, therefore we can just multiply the number of parts by the amount in each part
4 x 4 = 16
So there r 16 girls in the class
Answer:
70%
Step-by-step explanation:
B) In y = 25x, the value of y is 25 times the value of x, and in y = x + 25, the value of y is 25 more than the value of x.
Out of all the answer choices, b makes the most sense.
25x can be translated as 25 times x.
x + 25 can be translated as 25 more than a number.
Hope this helps!
