I need help with questions 1 and 2.

1. The integer is +5000.

2. The integer is -4.

Solution:

To write an integer that represents the given situation:

1. A plane flies at an altitude of 5000 feet.

Here, the distance between ground and plane is mentioned.

Plane is above the ground. So, it is positive integer.

The integer is +5000.

2. A swimmer is 4 feet below the surface of the water.

Here, also mentioned the distance between surface of water to swimmer.

But, it is below the ground. So, it is negative integer.

The integer is -4.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
