You can buy jars of the same jam in two sizes.

Vika [28.1K]

Answer:

Large Jar

Step-by-step explanation:

Large jar- 440g for £1.54

Cost per gram for the large jar = £1.54 ÷ 440g =£0.0035 per gram

Small jar- 340g for £1.26

Cost per gram for the small jar = £1.26÷ 340g =£0.0037 per gram

Since the cost per gram of the large jar is lower, <u>the large jar offers best value for money.</u>

Need help with finding my solution and graphing !

konstantin123 [22]

Answer:

Step-by-step explanation:

Both the equations that you modelled are correct.

Use the substitution method to solve the system of equations

$R+C = 526\\5R+4C=2327\\$

Take the first equation

$R+C=526\\C=526-R$

Now this becomes our third equation and now insert it into our second equation

$5R+4C=2327\\5R+4(526-R)=2327\\5R+2104-4R=2327\\R=2327-2104\\R=223$

Now insert R = 223 in any equation. Lets insert it into equation number three

$C=526-R\\C=526-223\\C=303$

So 223 number of roll papers were sold and 303 number of candles were sold.

I have attached the graph below check it out.

Where both the equations of line intersect is our solution thus we can confirm that our answer is correct.
