Lindsey earn $70 for working 5 hours. how much does she earn for working 12 lawns?
agasfer [191]
$70 for 5 hours = 70/5 for 1 hour.

70 / 5 = 14

That means $14 for 1 hour.

To find how much for 12 hours, multiply the price of 1 by 12 to get the price of 12 hours.

1 hour = $14
12 hours = 14 * 12

14 * 12 = 168.

That means the price of working for 12 hours is $168.

Hope this helped☺☺

CAN SOMEONE HELP ME ASAP
BARSIC [14]

Answer:

3 minutes

Step-by-step explanation:

To calculate this, you have to multiply 4.5 minutes by 8. This will give you the amount of pages that Wafa will print.

4.5 x 8 = 36 pages

Now that you have the amount of pages, you should divide it by the speed of the Sure-Fire printer. 12 ppm means that 12 pages can be printed in 1 minute.

36/12 = 3

Therefore, it would take 3 minutes if Wafa were to use her brother's Sure-Fire printer.
