Question

A store has apples on sale for $3.00 for 2 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $18.00? Complete the explanation.

Answer 1

Step-by-step explanation:

Here is what we need to remember.

1 pound = 16 ounces.

1 apple = 5 ounces

therefore.

1 pound = 16 / 5 = 3.2 apples

Now, we know that

$3.00 buys 2 pounds

therefore, $18.00 buys

`\$18*(2lb)/(\$3.00)`
`=6\cdot2lb=12lb`

This means that $18.00 buys 12 pounds of apples.

How many ounces are 12 pounds? The answer is

`12lb*(16oz)/(1lb)`
`=192oz`

Now, how many apples is 192 oz?

We know that 1 apple = 5 oz, therefore, 192 oz is

`192oz*\frac{1\text{apple}}{5oz}`
`=38.4`

Meaning you can buy about 38 apples for $18.00
