Barbara buys 3 boxes of eggs costing £1.20 each 1 jar of mayonnaise costing £1.80 2 loaves of breadshe pays £10 note and gets £1.60 change barbara works out the cost of 1 loaf of bread as £1.40

The cost of a box of eggs = $1.20

So, the cost of 3 boxes of eggs =

The cost of each jar of mayonnaise = $1.80

Let the cost of each loaf of bread = $'x'

So, the cost of 2 loaves of bread = = $2x

Since, Barbara gives $10 note and receives a change of $1.60.

Therefore, she pays for the given items.

Therefore,

So, x = 1.5

Therefore, the cost of each loaf of bread is $1.50 not $1.40.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
