A library has been given a specific amount of money and can buy 350 hardback books costing £15.75 each
a How many books costing £10.50 could be bought instead?
b What type of proportion does this represent

525 books

Step-by-step explanation:

Total books = 350

Cost of each book = £15.75

Total cost = 350 × £15.75

= £5,512.5

a. How many books costing £10.50 could be bought instead?

Instead of using £5,512.5 to buy 350 books at £15.75 each,

Number of books = total cost / cost per book

= £5,512.5 / £10.50

= 525 books

£5,512.5 can be used to buy 525 books at £10.50 each

The proportion is a direct proportion

1.true 2.false? ? i think. .

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
