Greg had 1/3 as many calendar to sell as Kenzo. The two friends decided to share the work evenly. To do that, Kenzo gave 10 calendars to Greg. What was the total number of calendars?
+37146 g = 1/3 k This is given in the Q
then k gives 10 to g and they are equal
g+10 = k - 10 sub in the red equation
1/3 k + 10 = k -10
2/3 k = 20
k = 30 g = 10 originally total 40 calendars
+318 Greg had 1/3 as many calendar to sell as Kenzo.
g = 1/3k
Get rid of fraction, multiply by 3
3g = k
The two friends decided to share the work evenly. To do that, Kenzo gave 10 calendars to Greg.
g + 10 = k - 10
g = k - 10 - 10
g = k - 20
replace k with 3g
g = 3g - 20
20 = 3g - g
20 = 2g
g = 20/2
g = 10 calendars
then
k = 3(10)
k = 30 calendars
:
What was the total number of calendars?
10 + 30 = 40
