By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation $\left \{ {{x+y=65} \atop {14x+7y=770}} \right.$ , we find that y=20 hours, which is Jack's maximum working hours.

Whats the error?katie divided 4.25 by 0.25 and a got a quotient of 0.17.

m_a_m_a [10]

The answer is 17. The decimal point needed to be moved by 2 places to the right since the divisor is a decimal.
