Answer:
The total price of
pounds of apples is <u>$6.48</u>.
Step-by-step explanation:
Given:
Last week,the price of apples at a grocery store was 1.60 per pound.This week,apples at the same grocery store are on sale for a 10% discount.
Now, to find the total price of 4 1/2 pounds of apples this week at the grocery store.
The price of apples at a grocery store last week was = $1.60 per pound.
This week apples at the same grocery store is on sale of 10% discount.
Thus, the price of apples at a grocery store this week is:
![1.60-10\%\ of\ 1.60.](https://tex.z-dn.net/?f=1.60-10%5C%25%5C%20of%5C%201.60.)
![=1.60-\frac{10}{100} \times 1.60](https://tex.z-dn.net/?f=%3D1.60-%5Cfrac%7B10%7D%7B100%7D%20%5Ctimes%201.60)
![=1.60-0.16](https://tex.z-dn.net/?f=%3D1.60-0.16)
![=\$1.44.](https://tex.z-dn.net/?f=%3D%5C%241.44.)
So, the price of apples per pound this week is $1.44.
Now, to get the total price of
pounds of apples by using unitary method:
If 1 pound of apples cost = ![1.44.](https://tex.z-dn.net/?f=1.44.)
Then,
pound of apples cost =
![=1.44\times 4.5](https://tex.z-dn.net/?f=%3D1.44%5Ctimes%204.5)
![=\$6.48.](https://tex.z-dn.net/?f=%3D%5C%246.48.)
Therefore, the total price of
pounds of apples is $6.48.
