What ever you do to one number you have to do to the other
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
Answer:
55.3
Step-by-step explanation:
First, take $64 and multiply it by .2.
You'll get an answer of 12.8, now subtract that from 64 to get 51.2.
Take 51.2 and multiply that by .08.
Add 4.1, (since we are rounding) to 51.2, to end with your answer: $55.30.
(25.45-12.5)+12.45
25.45-12.5
=12.95
12.95+12.45
=25.4 Is your answer
