Buying 10 cans for $5.80 is the best deal.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
We have
Cost of eight cans is $4.88
⇒ cost of one can = [tex]\frac{4.88}{8}[/tex] = $0.61
Cost of 10 cans is $5.80
⇒ cost of one can = [tex]\frac{5.80}{10}[/tex] =$0.58
Cost of 3 cans is $7.20
⇒ cost of one can = [tex]\frac{7.20}{3}[/tex] = $2.4
Hence, buying 10 cans for $5.80 is the best deal.
