Isla pick tomatoes from her vegetable patch and then sells them in boxes she changes 14p for each tomatoes and 25p for each boxe
amid [387]

9514 1404 393

Answer:

  • 18 tomatoes: £3.02
  • £4.39 ⇒ 26 tomatoes

Step-by-step explanation:

a) at 12 tomatoes per box, 18 tomatoes will require 2 boxes. Then Isla's price will be ...

  2(25p) +18(14p) = 50p +252p = £3.02

18 tomatoes in 2 boxes cost £3.02.

__

b) The 3 boxes cost 3(25p) = £0.75, so the tomatoes cost ...

  £4.39 -0.75 = £3.64

at 14p each, the number of tomatoes is £3.64/£0.14 = 26

There are 26 tomatoes in 3 boxes costing £4.39.

Assume that y varies directly with x, then solve.
Volgvan

Answer:

12

Step-by-step explanation:

y = kx

2⅔ = k(¼)

8/3 = k/4

k = 4×8/3 = 32/3

y = (32/3)x

y = (32/3)(1⅛)

y = (32/3)(9/8)

y = 3×4 = 12
