Answer 1

2.6

Explanation:

Given:

Sam bought 2 3/4 pounds of grapes for $ 7.15

Question asked:

What is the cost per pound ?

Solution:

By applying unitary method:

Cost of 2 3/4 pounds of grapes = 7.15

Cost of 1 pound of grapes =
`7.15/ 2(3)/(4)`

=
`7.15/(11)/(4)`

=
`7.15*(4)/(11)`

=
`28.6/11`

=
`2.6`

= 2.6

Thus, cost of grapes per pound is $2.6
