Answer:
Cost of 1 beef= $7.5
Cost of 1 bacon= $6
Step-by-step explanation:
Ok so first of organize everything:
We know she buys 6 pounds ->beef and 3 pounds ->bacon
First we need to set up an equation of how much 1 beef costs and 1 bacon costs:
Let’s say f=cost of 1 beef and b=cost of 1 bacon
Now lets make the equation:
6f+3b=63. (She buys 6 portions of beef and 3 bacon and her total comes out to 63)
Now their is another condition that the cost of one bacon is -$1.50 per pound than beef.
So we can say b=f-1.50
Do you notice anything similar? The b has a value now and so we can replace the b in our first equation with the b of the 2nd (b=b)
So hence,
6f+3(f-1.50)=63
6f+3f-4.5=63
9f=67.5
F=7.5 (This is the cost for 1 pound of beef)
Now lets find out for bacon,. Now instead of doing this equation all over again just insert it into the b=f-1.5 you know make life easier for yourself:
B=7.5-1.5
B=6
Cost of 1 beef= $7.5
Cost of 1 bacon= $6
