3.  x-pretzels
     y-granola
Lesley:   4x+2y=13.5
Landon: 1x+5y=17.55⇒x=17.55-5y

4*(17.55-5y)+2y=13.5⇒70.2-18y=13.5
x=17.55-5y

18y=56.7⇒y=3.15
x=17.55-5y⇒x=17.55-5*3.15⇒x=1.8

The cost for one bag of pretzels is $1.8, the cost for a box of granola bars is $3.15.

4. The wood bats: x-$24
    The metal bats: y-$30
Savelots sold 23 baseball bats: x+y=23
The receipts for those bats totaled $606: $24x+$30y=$606
x+y=23⇒x=23-y
24x+30y=606

x=23-y
24*(23-y)+30y=606⇒552-24y+30y=606

x=23-y
6y=54⇒y=9
             x=14
14 wood bats and 9 metal bats were sold.

The answer is d 18ft
