Variables and Assignments Practice Test

A temperature converter adjusts a reading. If the input value is 50, what will be the output value stored in celsius?

fahrenheit <- 50      // input temperature

celsius <- (fahrenheit - 32) * 5 / 9  // convert

celsius <- celsius + 2   // calibration adjustment

fahrenheit <- fahrenheit + 0 // unchanged input

celsius <- celsius       // keep adjusted value

A simple interest calculator updates the rate. Using the pseudocode below, what is the value of interest after executing the code?

principal <- 500      // starting money

rate <- 0.04          // initial rate

time <- 2             // years

rate <- rate + 0.01   // rate increases

interest <- principal * rate // one-year interest

interest <- interest * time  // total interest
