Fred works 30 hours a week between two parttime jobs a waite

Fred works 30 hours a week between two part-time jobs: a waiter ($9.25 per hour) and a math tutor ($8.5 per hour). Define a function t that determines the total amount of money Fred makes in a week in terms of the number of hours x he works as a math tutor. f(t) = 8.5x + (30 - x)9.25 t(x) = 8.5x + (30 - x)9.25 t(x) = 8.5x t(x) = 9.25x + (30 - x)8.5 Save

Let x no. ohrs he works as math tutor

earnings as tutor = x*8.5 = 8.5x
