If he pays with a £5 note and gets 30p change, that means the total cost was £4.70
All the items prices have to add up to £4.70
£1.18 + 94p = £2.12 so the two jars of jam together must cost £2.58 (£4.70 - £2.12).
If two jars cost £2.58 then one jar must cost half of that: £1.29
One jar = £1.29
The answer is B. 1. Exponents<span> add when you have the same base. This works for any </span>number<span> x that you want to plug in except for x = </span>0<span>,because </span>0/0<span> is indeterminate (it is like dividing </span>zero<span> by </span>zero<span>). No matter what </span>number<span> we use when it is </span>raised<span> to the </span>zero<span> power it will always be </span>1<span>.</span>
