Help on maths question +rep

[Kightly]

I've done all my other questions, just dont get this one on practise paper:

Sweets cost 5 pence each

Shamonti buys x sweets

Whats the expression, in terms of x, for the total cost?

A) x B) x C) x+5 D) 5 E) 5x
- -
5 x

[Caution]

For the total cost it would be 5(pence) x the amount of sweets so it'd be d) 5x

[Cyndia]

Yup, I second Caution. It's d) 5x.

[Charlottay!]

its 5x

[Jassim]

5x, you do understand why, right?

[DieselShaq]

Basically if Shamonti buys 1 sweet, the price would be 5 pence.
If Shamonti buys 2 sweets, the price would be 5 pence + 5 pence = 10 pence.
So if you substitute the amount of sweets with x, the equation for the total price would be x amount of 5 pence added together, which is 5*x, which is simplified to 5x.

The answer is therefore E) 5x

an easier was is thinking 5 sweets at 5p would be 5 x 5 so x sweets at 5p would be 5 x X which is writen as 5x :) xox

an easier was is thinking 5 sweets at 5p would be 5 x 5 so x sweets at 5p would be 5 x X which is writen as 5x :) xox

haha I think thats more complicated.

1 sweet = x
2 sweets = 2x
3 sweets = 3x
4 sweets = 4x
5 sweets = 5x

If a sweet costs 10p, and you buy say 10, you are going to pay:

10 sweets * 10p = 100p

so lets say x = 10

now if you buy 5 sweets
it becomes

5 sweets * x = 5x ... which is the same as 5*10p = 50p :)

Hope that explains it.
