A sports shop in Manchester is doing a sale on some merchandise. Liz hears about it and goes to make a purchase of two pairs of running shoes. She gives the sales
attendant in the store three crisp £50 notes and is given change of £10.50. What is
the price of each pair of running shoes? Show your working

£69.75

Step-by-step explanation:

Given

No. of pairs of shoes bought by Liz = 2

she gave attendant  three crisp £50 notes

total money given by Liz = £50*3 = £150

Money she was returned = £10.50.

thus, the money kept with attendant is price of two pair of  shoes

price of 2 pair of shoes = total money given by Liz  - Money she was returned

price of 2 pair of shoes =  £150 - £10.50 = £139.50

To find price of 1 pair of shoes we divide both LHS and RHS by 2

price of 2/2 pair of shoes =   £139.50/2 = £69.75

price of 1 pair of shoes =  £69.75  Answer

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
