On Friday morning the temperature was 67°F. The temperature dropped 6°F and then rose 10°F. How much does the temperature need to rise or fall to return to the initial temperature of 67°F?(1 point)
The temperature dropped 6°F, so it was at 67°F - 6°F = <<67-6=61>>61°F.
The temperature then rose 10°F, so it was at 61°F + 10°F = <<61+10=71>>71°F.
Therefore, the temperature needs to fall 71°F - 67°F = <<71-67=4>>4°F to return to the initial temperature of 67°F. Answer: \boxed{4}.
To find out how much the temperature needs to rise or fall to return to the initial temperature of 67°F, we can track the total change in temperature.
The initial temperature is 67°F.
The temperature then dropped by 6°F, so the temperature is now 67°F - 6°F = 61°F.
Next, the temperature rose by 10°F, so the temperature is now 61°F + 10°F = 71°F.
To return to the initial temperature of 67°F, the temperature needs to fall by 71°F - 67°F = 4°F.
Therefore, the temperature needs to fall by 4°F to return to the initial temperature of 67°F.
