Answer :
Since 2 pounds is $3 and you have $9, you would do:
[tex] \frac{3}{2} = \frac{9}{x} [/tex] , x= # of pounds of apples
You do cross multiplication to get:
[tex]3x=18[/tex]
x=6
1 lb= 16 oz
So [tex]6*16=96[/tex] to get the number of ounces you can buy for $9.
Then divide 96 by 5, so that is ABOUT 19 APPLES.
[tex] \frac{3}{2} = \frac{9}{x} [/tex] , x= # of pounds of apples
You do cross multiplication to get:

1 lb= 16 oz
So [tex]6*16=96[/tex] to get the number of ounces you can buy for $9.
Then divide 96 by 5, so that is ABOUT 19 APPLES.
we know that
A store has apples on sale for $[tex] 3.00 [/tex] for [tex] 2 [/tex] pounds
Part a) How many pounds of apples can you buy for $[tex] 9 [/tex]?
by using proportion
[tex] \frac{3}{2}\frac{usd}{pound} =\frac{9}{x} \frac{usd}{pound} \\ \\ 3x=9*2\\ \\ x=\frac{18}{3} \\ \\ x=6 pounds [/tex]
therefore
the answer Part a) is
[tex] 6 pounds [/tex]
Part b) If an apple is approximately [tex] 5 [/tex] ounces, how many apples can you buy for $[tex] 9 [/tex]?
we know that
[tex] 1 pound=16 ounces [/tex]
step 1
convert ounces to pounds
[tex] 1apple=\frac{5}{16}pounds [/tex]
by using proportion
[tex] \frac{1}{\frac{5}{16}}\ \frac{apples}{pounds} =\frac{x}{6} \frac{apples}{pounds}\\ \\ x\frac{5}{16} =6\\ \\ x=\frac{16*6}{5} \\ \\ x=19.2 apples [/tex]
therefore
the answer part b) is
about [tex] 19 apples [/tex]
