Question

Julie buys 2kg of apples and 7 kg of pears for £12.70. The pears cost £1.30 per kilogram. What is the price per kilogram of the apples?

Step-by-step explanation:

find the price of pears

7kg * 1.30£ = 9.1£

from the total price take away the cost of pears

12.70 - 9.1 = 3.6 £ (price of 2Kg of pears)

3.6 : 2 = 1.80 £ ( cost of 1 Kg of apples)

or you can solve with an expression

12.70 - (7 * 1.3) : 2 =

1.80 £

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

for future students the answer is b
