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.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
