Question

The total cost of 3 1/2 pounds of meat at $1.69 per pound and 20 lemons at 60 cents per dozen will bea.$6.00b.$6.40c.$6.52d.$6.82e.$6.92

Answer 1

e. $6.92

Explanation:

The cost of 1 pound of meat = $1.69

`\text{ The cost of }3(1)/(2)\text{ pounds of meat }=3.5*1.69=\$5.92`

Similarly, the cost per dozen of lemons = 60 cents

`\begin{gathered} \text{ The cost of 1 lemon}=(60)/(12)=5\text{ cents} \\ \implies\text{ The cost of 20 lemons}=5*20=100\text{ cents}=\$1 \end{gathered}`

Add the two to find the total cost:

`\begin{gathered} \text{ Total Cost}=5.92+1 \\ =\$6.92 \end{gathered}`

The total cost of 3 1/2 pounds of meat at $1.69 per pound and 20 lemons at 60 cents per dozen will be $6.92.

Option E is correct.
