I need help on this exercise:

A person's paycheck (p) varies directly as the number (h) of hours worked. For working 15 hours the pay is $236.25. Find the pay for 35 hours of work.

well what you need to do is divide 15 by $236.25 and then when you get the anwser you have to multiply that by 20 because 15 subtracted by 35 equals 20 and then u will get ur anwser

A person's paycheck (p) varies directly as the number (h) of hours worked. For working 15 hours the pay is $236.25. Find the pay for 35 hours of work.

Variation exercises translate as follows:

. . . . ."y varies directly as x": y = kx

. . . . ."y varies inversely as x": y = k/x

. . . . ."y varies jointly as x and z": y = kxz

Plug the given information into the appropriate equation type (using "p" for "y" and "h" for "x", naturally). Solve for the value of the variation constant "k". Then plug "35" into the formula, and simplify to find the requested value.

If you get stuck, please reply showing how far you have gotten. Thank you.

Isosa is correct.

3 apples cost 75 cents;

so 1 apple costs 25 cents;

then 9 apples cost 9 times 25 cents = $2.25 : capish?
