How much do the hamburgers cost? ** The cost of 5 hamburgers is 5 x $4 = $<<5*4=20>>20.
How much do the potato fries cost? ** The cost of 10 packs of potato fries is 10 x $0.30 = $<<10*0.3=3>>3.
How much do the fruit drinks cost? ** And, the cost of 5 cans of fruit drinks is 5 x $2 = $<<5*2=10>>10.
What is the total cost? ** Thus, the total cost is $20 + $3 + $10 = $<<20+3+10=33>>33.
How much change does Carly get back? ** Therefore, Carly gets a change of $50 - $33 = $<<50-33=17>>17.
