I’m not extremely good at math but I think you need to make -x-y=1 into y=mx+b form and then solve your new equation!
Answer: the large jar is cheaper
Step-by-step explanation:
If you divide the £1.54 by 440g and £1.26 by 340g, you'll find which one is cheaper per gram :
1.54/440 = 0.0035
1.26/340 = 0.0037
So, by comparing both prices/gram, you've found that the large jar is cheaper.
To solve this problem, you can make a proportion:
3/900 = x/2100
In this case, the x represents the pounds that will be needed to cover 2,100 feet.
The first step is to cross multiply like this:
3 * 2100 = 900 * x
Now you can simply the equation.
6300 = 900x
Now you divide both sides by 900 to cancel it out.
7 = x
So, your answer is 7 pounds.
