Answer:

Equation: 24 - 2p = 10

Pencils she bought: 7 pencils

Explanation:

Let number of pencils be p

initial money - cost of pens = final money

24 - 2p = 10

Solve this to find pencils she bought:

24 - 2p = 10

-2p = 10 -24

-2p = -14

p = 7

So she bought 7 pencils in total.

On average during the summer, a 30,000 cubic foot house costs $7 per day to cool, while a 25,000 cubic foot house costs $6.50 pe
Ber [7]

The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.

Step-by-step explanation:

The cost of cooling 30000 cubic foot house = $7

Cost per cubic foot = 7/30000

=$0.00023

The cost of cooling 25000 cubic foot house= $6.50

Cost per cubic foot=6.50/25000

= $0.00026

The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
