Question

Joaquin recorded a temperature of 62°F this morning for science class. The temperature increased 6 1/2°F in the afternoon before decreasing 8.7°F in the evening. What was the evening temperature?

Answer 1

Add 6.5 to 62 then subtract 8.7 to get 59.8

Answer 2

Answer:
`59.8^(\circ) F`

Explanation:

Given : Joaquin recorded a temperature of 62°F this morning for science class.

The temperature increased
`6(1)/(2)^(\circ)F` in the afternoon before decreasing 8.7°F in the evening.

We can write
`6(1)/(2)` as
`6+(1)/(2)=6+0.5=6.5` .

Now According to the question , the temperature at evening will be :-

`62^(\circ)F+6(1)/(2)^(\circ)F-8.7^(\circ)F\\\\=62^(\circ)F+6.5^(\circ)F-8.7^(\circ)F\\\\=(62+6.5-8.7)^(\circ)\ F=59.8^(\circ)\ F`

Hence, the evening temperature was
`59.8^(\circ) F` .
