Let x= the number of books purchased: 7 books purchased
let y = the number of toys purchased;10 toys purchased
Equations: x+y=17
6x+11y=152 x+10=17
-6(x+y=17) y=10 -10 -10
------------
-6x-6y=-102 x=7
6x+11y=152
--------------------
0x+5y=50
---- ----
5 5
For this, we need to find the lowest common multiple of 12 and 15....
common multiples of 12 : 12,24,36,48,60
common multiples of 15 : 15,30,45,60
LCM = 60
the caller that will be the first to win both is the 60th caller
9.8t^2-49t+40=0
t=(49±√833)/19.6
t≈1.027, 3.97
1.027<t<3.97
