Answer:

Choices A, C, E

Step-by-step explanation:

The prices are proportional, so divide any price by the corresponding number of pounds to find the unit cost.

$1.47/(3 lb) = $0.49/lb

The unit cost is $0.49 per lb.

Now we look in the choices to see which choice has a unit price of $0.49/lb.

We divide each price by its number of pounds to fund each unit cost. Every choice with a unit cost of $0.49/lb is an answer.

A $0.98/(2 lb) = $0.49/lb Choice A works

B $4.45/(7 lb) = $0.64/lb Choice B does not work

C $2.94/(6 lb) = $0.49/lb Choice C works

D $0.54/(1 lb) = $0.54/lb Choice D does not work

E $3.92/(8 lb) = $0.49/lb Choice E works

Answer: Choices A, C, E

Choices A, C, E should be selected.

Since the prices are proportional, so here we divide any price by the corresponding number of pounds to determine the unit cost.

So,

$1.47 ÷ (3 lb) = $0.49/lb

The unit cost is $0.49 per lb.

Now we look in the choices

A $0.98 ÷(2 lb) = $0.49/lb

B $4.45 ÷(7 lb) = $0.64/lb

C $2.94 ÷(6 lb) = $0.49/lb

D $0.54 ÷ (1 lb) = $0.54/lb

E $3.92 ÷(8 lb) = $0.49/lb
