    of course you do

    Always relate to a number situation

    How would you change £7 into pence

    Would it be something along the lines of:

    50-x=y

    850/x

    850/y

    or x+y=50
    50-x=y

    850/x

    850/y

    How about:
    \ 25(50 -x) + 15x = 850 Do you see what I did here?

    Yeah i get it, so this will give me;

    1250-25x+15x=850

    Would something else need to be done to this equation now?

    I'm assuming you want a direct solution so here goes:

    1) a.
    The basic cost is £P. Then x pence is added per mile driven. x pence is
    £(x/100). So the total cost in pounds is £P+(x/100).

    b.
    You can convert the previous answer by multiplying by 100 to get:
    100P+x pence

    2) a.
    The shopper buys 50 fruit. x are oranges. Logically speaking, the lemons must be what is left over from 50 after x orange so the number of lemons would be 50-x

    b.
    Since lemons cost 25 pence you simply multiply the number of lemons by 25 pence/lemon which gets you 1250-25x pence {just 25(50-x) works too - its easier to use for mental arithmetic and is simplified}

    c. The shopper has bought x oranges at 15 pence each so the total cost is 15x pence.

    (The last two answers can be converted to punds as well)

    d.
    x*orange's cost + (50-x)*lemon's cost = 850 (I converted it to pence for simplicity)
    This simplifies to:
    15x + 25(50-x) = 850 (Keep going from here
    15x + 1250 - 25x = 850
    15x - 25x = 850 - 1250
    -10x = -400
    x = 40

    You wrote find the cost of the lemons but thats already given as 25 pence. I'm assuming you meant number of lemons so:

    Since x is the number of oranges and 50-x the number of lemons, the shopper bought 40 oranges and 10 lemons. {50-40=10}

    Hope this helped

    Oh sorry about that, I'm new and everything. I tried to walk through all the steps so it wasn't just the answers. Is it possible to add a spoiler tag?

    Hit edit then go advanced. Highlight the text and click on the thing next to the you tube link.
    Alternatively just type [spoiler] [/spoiler
    Close the square bracket on the other side and a spoiler will appear.
