Answer:
The total price of [tex]4\frac{1}{2}[/tex] pounds of apples is $6.48.
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:
[tex]1.60-10\%\ of\ 1.60.[/tex]
[tex]=1.60-\frac{10}{100} \times 1.60[/tex]
[tex]=1.60-0.16[/tex]
[tex]=\$1.44.[/tex]
So, the price of apples per pound this week is $1.44.
Now, to get the total price of [tex]4\frac{1}{2}[/tex] pounds of apples by using unitary method:
If 1 pound of apples cost = [tex]1.44.[/tex]
Then, [tex]\frac{9}{2}[/tex] pound of apples cost = [tex]1.44\times \frac{9}{2}[/tex]
[tex]=1.44\times 4.5[/tex]
[tex]=\$6.48.[/tex]
Therefore, the total price of [tex]4\frac{1}{2}[/tex] pounds of apples is $6.48.
