4 x 12 is 48 and then plus 20 is 68
ANswer to 1 is 68.
4 hours for 68 miles
If we let x as the total number of baseball cards
and yn be the quotient per operation, then
x/17 = y1 + 3
x/16 = y2 + 10
x/11 = y3 + 4
x/7 = y4
Based on Equation 1, x must be greater than 17
Based on Equation 4, x must be divisible by 7
y1, y2, and y3 must all be whole numbers
