Question

A pound of swiss cheese costs $4.00 at the grocery store. Use the

fact that 16 ounces = 1 pound to help you find the cost of 2 1/2 pounds
of swiss cheese.
a. $2.00 c. $8.00
b. $12.00 d. $10.00

Answer 1

he cost of
`2(1)/(2)` pounds of cheese s $10

Solution:

Method 1:

Cost of one pound of cheese = $4

Cost of 2 pounds of cheese =
`\$4*2=\$8`

Cost of
`(1)/(2)` pound of cheese =
`\$4*0.5=\$2`

Therefore, the cost of
`2(1)/(2)` pounds of cheese = 8+2=$10

Method 2:

If one pound of cheese costs $4 then, the cost of
`2(1)/(2)` (i.e 5/2) pounds of cheese =
`\$4*(5)/(2)=\$10`

Therefore,
`2(1)/(2)` pounds of cheese costs $10
