Answer:
6 jogs
Step-by-step explanation:
To spend exactly $50
Jags = $1
Jigs = $2
Jogs = $7
If he must buy atleast 1 of each and still spend exactly $50
Hence, the largest number of jogs he can buy can be modeled as :
First obtain the multiples of 7 up to 50
Multiple of 7 up to 50
7 : 7, 14, 21, 28, 35, 42, 49
If $49 is spent on jigs, then he won't be able to purchase jigs.
Hence, the largest amount he can spend on jogs is $42
Thus, he can buy $42 / $7 = 6 jogs
The $8 left can be spent on jigs and jags
