Answer:
He must earn $2,400 to cover both leisure and $2,160 for school expenses.
Step-by-step explanation:
Let the total amount Ken must earn be k. Then 10% of that would cover leisure activities and the remaining 90% specifically for school expenses.
Then 0.90k = $2,160, and k = $2,400.
He must earn $2,400 to cover both leisure and $2,160 for school expenses.

Hey there
Lets solve this question together,
Convert 76.8% to a decimal.
0.768 * x=40.32
Multiply 0.768 by x to get 0.768x.
0.768x=40.32
Multiply each term by 1 / 0.768 and simplify.
Cancel the common factor of 0.768.
x=40.32 / 0.768
Divide 40.32 by 0.768 to get 52.5
x=52.5
Answer:
x = 3/4
Step-by-step explanation:
It usually works well to collect terms first. (Add the coefficients of x.)
-4x +x = -9/4
(-4+1)x = -9/4
-3x = -9/4 . . . . . . equation with terms collected
Now, you can divide by the coefficient of x. Here, it can be useful to consider this to be the same as multiplying by the inverse of that coefficient, which inverse is -1/3.
(-1/3)(-3x) = (-1/3)(-9/4) . . . . . multiply both sides by -1/3
x = 3/4 . . . . . simplify
