Maggie's oven is malfunctioning. When she sets it to 450 the actual temperature is 468. If it's off by the same percentage for any recipe, what temperature should she set it at if her recipe calls for 520 degrees?
How many degrees is the oven off by? ** The oven off by 18 degrees because 468 - 450 = <<468-450=18>>18
How many percent is the oven off by? ** The oven is off by 4% because 18 / 450 x 100 = <<18/450*100=4>>4%
Write an equation ** Therefore X + .04X = 520
Simplify ** Therefore 1.04X = 520
How many degrees is the temperature to set it at? ** The temperature to set it is 500 because 520 / 1.04 = <<520/1.04=500>>500
#### 500
