Problem Solving

Angelica and Eliza are arguing about a problem on a math worksheet. Angelica says that 12² = 24 because you multiply 12 by the number on top. Eliza says that 12² is equal to 144, because you multiply the base as many times as it shows on the top. Who is correct? Explain your Thinking.

Eliza is correct. I know this because in order to find the answer to an exponent, you multiply the base number as many times as the exponent telle you to. For example, 12² is also equal to 12 x 12 = 144. Therefore, Eliza is correct.

Yoda is tilling his 4 m x 4 m floor. He goes to Home Depot to buy some 5 dm x 5 dm tiles, but needs to figure out how much he needs. Can you teach Yoda to figure out how many tiles he needs? 

No, I will not teach Yoda! 

First, you must convert 5 dm into m. 

5 dm = 0.5 m 

Then, 4 ➗ 0.5 = 8 two times

Lastly, you multiply 8 by 8, which gives you 64 tiles needed.

Rico is at the local Curry’s,to buy paint. Her canvas is   27 cm x 27 cm and costs $24. Each bottle of paint she buys covers 3 cm of the canvas. Each bottle of paint costs $2. How much money does Rico spend?

27 ➗ 3 = 9 bottles used

$2 x 9 = $18

$18 + $24 = $42

Rico spends 42 dollars.

Emma played 6 games of tennis. She scored 76 points in the first game, 88 points each in the next two games and 92 points for the following two games. She scored 515 points altogether. Write the expression and calculate the number of points she scored in the last game.

76+(88x2)+(92➗2)

= 76+176+(92➗2)

= 76+176+46

= 298

515-298=217

217 points scored in the last game

Inky brings $85 450 to buy tiles. She has at room that is 30m². If she wants to tile the room using 5 cm x 5 cm, one tile costing $8, how much more money needed? If not, how much change does Inky get back?

30m²= 5m x 6m

5m= 500cm

6m= 600cm

500➗5= 100

600➗5= 120

100 x 120= 12 000

12 000 x 8= 96 000$

$96 000-$85 450= $10 550

Inky needs $10 550 in order to buy the tiles.
