Answer:
No, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Barbara buys 3 boxes of eggs costing £1.20 each
1 jar of mayo costing £1.80
2 loaves of bread
she pays £10 note and gets £1.60 change
Barbara works out the cost of 1 loaf of bread as £1.40.
Is she correct? You MUST show your working out.
The explanation of the answer is now given as follows:
Total cost of 3 boxes of eggs = Number of boxes of eggs bought * Price per box of egg = 3 * £1.2 = £3.60
Cost of 1 jar of mayo = £1.80
Total amount spent = Note paid - Change collected = £10 - £1.60 = £8.40
Total cost of 2 loaves of bread = Total amount spent - Total cost of 3 boxes of eggs - Cost of 1 jar of mayo = £8.40 - £3.60 - £1.80 = £3.00
Cost of 1 loaf of bread = Total cost of 2 loaves of bread / 2 = £3.00 / 2 = £1.50
Therefore, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
In miles 365 million miles or 365,000,000
in km, 588 million km or 588,000,000
so
scientific notation=(number less than 10 and greater than or equal to 1) times 10^n
so
we need to move the decimal point 8 spaces to the left
to compensiate for that, we multiply by 10⁸ which will move it 8 to the right
so
365,000,000 mi=3.65 times 10⁸ mi
588,000,000 km=5.88 times 10⁸ km
those are the distances in scientific notation
