Question

lexi went to the store to purchase apples which cost $1.08 per pound. she purchased 1 1/2 pounds pf green apples and 3/4 of red ones. how much did the apples cost?

Answer 1

Lexi purchased
`1(1)/(2)` pounds of green apples and
`(3)/(4)` pounds of red ones. In total, she purchased

`1(1)/(2)+(3)/(4)=(3)/(2)+(3)/(4)=(3\cdot 2+3)/(4)=(9)/(4)` pounds of apples.

If apples cost $1.08 per pound, then the total cost is

`\$1.08\cdot (9)/(4)=\$(108)/(100)\cdot (9)/(4)=\$(54)/(50)\cdot (9)/(4)=\$(27\cdot 9)/(50\cdot 2)=\$(243)/(100)=\$2.43.`

Answer: $2.43
