# A computer repair service charges a one-time bench fee of \$50 to diagnose the problem and \$35 per hour to repair it. . • Write an equation in the form y = mx + b that relates the total cost y to the number of hours the repair takes x. Identify the slope and the y-intercept in your equation. What do they mean in the context of this problem? If a computer takes 5 hours to repair, how much will it cost? If a computer costs \$242.50, how long did it take to repair it? . .   ### Other questions on the subject: Mathematics Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is \$45,000 with a standard deviation of \$9,200. for a sample of 25 subscribers to plan b, the mean income is \$64,300 with a standard deviation of \$7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule?
