answer: total gross profit is $ 2791
since, the total revenue by sales = $ 9,489,
total returned = $ 225
cost of goods = $ 5481,
and, operating expenses = $ 992
thus, the gross profit = total revenue - direct costs of producing that good or service = 9489 - ( 225 + 5481 + 992) = $ 2791
therefore, there was a gross profit of $ 2791 on the sale.
a ruler? idk
hello from mrbilldoesmath!
27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
let f(t) - 9 sqrt(t) sin(t), then
y' = f(x^3) * d(x^3)/dx - f(sqrt(x)) * d(x^1/2)/dx
= (9 sqrt(x^3)sin(x^3)) * 3x^2 - (9 sqrt(x^1/2)sin(x^1/2)) * (1/2) x^-(1/2)
= 27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
hope i didn't make a "bozo" error differentiating things!
the most important part of the problem lies in the fact that the hours have to be converted to minutes before starting to solve the problem.
1 hour = 60 minutes
6 and half hours = (6 * 60) + 30 minutes
= 360 + 30
= 390 minutes
so the payment for 390 minutes is = 78 dollars
the payment for 60 minutes = (78/390) * 60
= 2 * 6 dollars
= 12 dollars
so the rate of pay given is $12 per hour. i hope the procedure is easy enough for you to understand. you can always use this method for solving similar type of problems.
