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)

Answer:
y=3x-4
Step-by-step explanation:
PEMDAS is the steps to do Order of operations...
P- parentheses
E- exponents
M- Multiplication
D-Division
A- Addition
S- Subtraction
You do p first e next then either m or d then a or s
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.
