Answer 1

C)

Explanation

Step 1

check every option

A)The temperature falls 1.9°F from 4.3°F.

$\text{the change in the temperature is 4.3-1.9=2.4}$

B) A hot air balloon rises 4.1 meters from the ground

and then rises 2.3 meters more.

$\text{change in height = 4.1 mt +2.3 mt=6.4}$

C) A submarine goes 3.8 feet below the surface of the

ocean and then goes 2.5 feet farther down.

$\text{change in depth = -3.8-2.5=-6.3}$

D) The amount of money Sarah has after she buys milk

for $3.85 and bread for $2.45.

$\text{the total amount = 3.85+2.45=4.3}$

Step 2

compare

the number that approximates more to -7 is

$-6.3\Rightarrow C)$
