Question

Murphy loves pistachio nuts. Every Saturday morning, she walks to the market and buys some. Last week, she bought two pounds and paid $7.96, and this week she bought only one-half pound and paid $1.99. What the unit rate for pistachio nuts?

Answer 1

$3.98

Explanation:

To answer this, we can use simple division and multiplication.

Using the example of 2 pounds is equal to $7.96:

If 2 pounds = $7.96, then...

1 pound = ($7.96) divided by 2

1 pound = $3.98

Using the example of half a pound is equal to $1.99:

If 0.5 pounds = $1.99, then...

1 pound = ($1.99) x 2

1 pound = $3.98
