Jane pulled weeds in the garden 7 times. She was paid $5 each time she pulled weeds for less than 1 hour and $6 each time she pulled weeds for more than 1 hour. If Jane received $39, how many times did she pull weeds for more than 1 hour?

Respuesta :

Given:

$5 each time she pulled weeds for less than 1 hour and $6 each time she pulled weeds for more than 1 hour

Required:

Times Jane pulled weed for $39 for more than an hour

Solution:

 For 1 hour: $5 x 7 = $35

For more than 1 hour: $6 x 7 = $42

 

$39 - $35 = $4

$4/$6 = 2/3 times

 

So 7 times plus 2/3 = 7.67 times
