Question 202307
<font face="Garamond" size="+2">

6 for 1 garden
11 for 2 gardens
16 for 3 gardens


You add 5 for each additional garden.


So for the first garden you need 5 + 1
for the second garden you need 5 + 5 + 1
and for the third you need 5 + 5 + 5 + 1


This suggests that if *[tex \Large y] is the number of stones and *[tex \Large x] is the number of gardens, the relationship:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y = 5x + 1]


holds.


For 18 gardens, just substitute 18 for *[tex \Large x] and do the arithmetic.
