Answer 1

Solution:

Money Barbara gave to shopkeeper = £10

Money used as Barbara got £1.60 back = £10 - £1.60 = £8.40

Barbara buys 3 boxes of eggs costing = 3 x £1.20 = £3.60

Barbara buys 1 jam costing = £1.80

Barbara buys 2 loaves of bread = Total money used - (Eggs cost + Jam cost)

                                                     = £8.40 - ( £3.60 + £1.80 )

                                                     = £8.40 - £5.40

                                                     = £3.00

Cost of 2 loaves of bread is = £3.00

Cost of 1 loaf of bread will be = £3.00 / 2 = £1.50

Solution:-

here ,

firstly we will find the total cost of all the things

$3boxes \: \: of \: \: eggs \: \: cost = 3 \times 1.20 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.60 \\ \\ total \: cost \: of \: egg \: \: and \: jam = 3.60 + 1.80 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5.40 \\ \\ now \: for \: 2bread \: loaf \: price \: \\ \\ egg \: + jam + bread \: loaf = 10 \: \: \: \: \: ..........(given) \\ \\ 5.40 + bread \: \: loaf = 10 \\ \\ bread \: loaf = 10 - 5.40 \\ \\ bread \: loaf \: = 4.60 \\ \\ here \\ \\ 2 \: bread \: \: loaf \: price \: = 4.60 </p><p>now,</p><p>she get 1.60 money back</p><p></p><p>so</p><p>4.60 - 1.60 = 3\\ \\ for \: 1bread \: \: loaf \: \: price = \frac{3}{2} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1.5$
