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
Answer:
They sold
20 Roses and 20 Carnations
Step-by-step explanation:
The total sales of 40 flowers is $100 not $10 as in the question
Roses=$3
Carnations=$2
Total flowers sold=40
Total sales=$10
Let Roses=r
Carnations=c
c+r=40. (1)
3r+2c=100 (2)
From (1)
c=40-r
Substitute c=40-r into (2)
3r+2c=100
3r+2(40-r)=100
3r+80-2r=10
r=100-80
r=20
Substitute r=20 into (1)
c+r=40
c+20=40
c=40-20
=20
c=20
r=20
Check:
3r+2c=100
3(20)+2(20)=100
60+40=100
100=100
5 x 3/4 = 15/4
15/4 = 3 3/4
