Question

Noah’s oven thermometer gives a reading that is 2% greater than the actual temperature

If the thermometer reading is 76°F, what is the actual temperature?

Note: sorry for my ugly handwriting

Answer 1

Answer:

Part a) $331.5\°F$

Part b) $74.51\°F$

Step-by-step explanation:

Let

x--------> the actual temperature

y-----> the thermometer reading temperature

we know that

$y=1.02x$ ------> linear equation that represent the situation

Part a) we have

$x=325\°F$

substitute in the linear equation and solve for y

$y=1.02(325)=331.5\°F$

Part b) we have

$y=76\°F$

substitute in the linear equation and solve for x

$76=1.02x$

$x=76/1.02=74.51\°F$
