Peaches are on sale for 1.89 a pound, including sales tax. Cindy plans to buy 2.5 pounds of peaches. How much money does cindy need to purchase the peaches

Answer 1

Hi Tremayne,

If peaches are $1.89 a pound, that means that to buy 1 pound of peaches, Cindy needs $1.89. To buy a second pound of peaches, she needs another $1.89.

To buy two pounds, we can write that Cindy needs $1.89+$1.89 = $3.78. This is the same as writing $1.89X2 = $3.78. Multiplying by 2 means we want to know how much two groups of $1.89 is.

In general, we just put Money a Pound X Number of Pounds = Money Cindy Needs

To buy 2.5 pounds, we want to know how much 2.5 groups of $1.89 is (because 1 pound costs $1.89). The fastest way to solve this is by using the multiplication. So:

1. $1.89 X 2.5 = $4.725 <---- Here, we will round up to $4.73 because $0.005 is less than a penny. When we round, if the number is 5 or higher, we round up.

So, Cindy needs $4.73 to buy 2.5 pounds of peaches.
