One way to solve it is writing two equations based on the info so
y = 5x + 10 for members
y = 6x for nonmembers
(the + 10 isn't included in the second equation because nonmembers won't pay a membership fee)
and to find their intersection point (where the values will be the same), you just set them equal to each other:
5x + 10 = 6x
subtract 5x
x = 10 classes
Answer:
67/100
Step-by-step explanation:
67÷100 Divide the numbers
0.67 then move the decimal point to the right
6.7 *10 this will give you the fraction
Given problem is 
To simplify that we need to multiply and divide by conjugate of the denominator
conjugate of denominator 6+i will be 6-i as we just need to change sign of the imaginary part
Now multiply and divide by 6-i
Hence final answer is 
Answer:
3/40
Step-by-step explanation:
1/4 x 1/3 - 1/5 x 1/4 +1/4 x 1/6
(1/4 x 1/3) - (1/5 x 1/4) + (1/4 x 1/6)
1/12 - 1/20 + 1/24
1/30 + 1/24
3/40
