Mathematics: 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

21/5=4.2 she should put markers every 4.2 feet...

Noah’s oven thermometer gives a reading that is 2%

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

$x=76/1.02=74.51\°F$
