If you think about it, 4x7 is half of 8x7 (If you multiply 4, 7, and 2, you get 8x7). So really you can just multiply 4x7 by 2 and you will get 8x7!

Jorge makes 59.50 an hour for working at a Shoe Store. He wants to buy a skateboard that costs $110,00. How many hours must Jorg
siniylev [52]

Answer:

2 hours

Step-by-step explanation:

Since he gets 59.50 every hour you'll need to see how much 59.50 can go into 110$

So, 110/59.50 = 1.8487395

You can then round this number up.

Since he's paid by the hour he'll need to work 2 hours but he'll still have a bit of money left over
