How much do 5 lollipops cost? ** Five lollipops cost $0.4 x 5 = $<<0.4*5=2>>2.
How much do 4 candies cost? ** So four candies cost $3.20 - $2 = $1.20.
How much does each candy cost? ** Thus, each candy costs $1.20/4 = $<<1.20/4=0.30>>0.30.
How much do 10 lollipops cost? ** Ten lollipops cost $0.4 x 10 = $<<0.4*10=4>>4.
How much do 10 candies cost? ** Ten candies cost $0.30 x 10 = $<<0.30*10=3>>3.
How much will 10 lollipops and 10 candies cost him? ** Hence, 10 lollipops and 10 candies will cost $4 + $3 = $7.
