Ian’s monthly allowance is $21. In January he starts saving for a birthday gift in June. Each month he saves 2/3 of his allowanc
Art [367]

He starts saving $ in January to buy a gift in June. (which is 6 months, or 5 months not including June)

Each month he saves 2/3 of his allowance, which is $14.

[his allowance each month is $21, 2/3 of his allowance is $14]

(you multiply 21 by 2/3 = 42/3 = 14)

The gift he wants to buy is $110


x = the number of months

y = total cost


14x = y  

14x = 110    [he saves $14 each month, he wants to have a total of $110 to buy a gift]


Plug in 6 for x in the equation

14(6) = 110

84 = 110   (He is $26 short, so saving either for 5 or 6 months will not get Ian $110)


Ian will not have enough money because he is $26 short for 6 months or $40 short for 5 months. (you can decide whether you want to go by 5 months or 6(including June), sorry for the confusing answer)

Find the cost of 100gram at 85p per 1/2 kg?
Yuki888 [10]
85p per (1/2) kg.

1 kg = 1000g,  (1/2)kg = (1/2) * 1000 = 500 g

It means:

500g cost 85p

1g would cost  85p/500

100g would then cost      (85p/500) * 100 = 19p

Cost of 100g is = 19p

Hope this explains it.
