Answer:
Part A: $55.50
Part B: 52 hamburgers(sorry if I am wrong for part b but I think it is right)
Step-by-step explanation:
Part A: $14.50 x 3= $43.50 + 24 x $0.50= $12=
($ earned per hrs x hrs worked)+ ($ per hamburger sold x times amount)
Hence $43.50 + $12= $55.50.
Part B: $14.50 x 6.5 = $94.25 $120 - $94.25= $25.75
($ earned per hrs x hrs worked x x hrs worked) ($ earned - $ earn from shif
$25.75/0.50=51.5 (51.5 rounded to nearest burgers is 52 burgers)
Hence answer is 52 burgers.
