Don't know if it's right, but do let me know! use percentage to visualise your workings. :)
Answer:
$16
Step-by-step explanation:
Let his weekly allowance = x
Amount spent playing golf = x / 2
Amount earned for cleaning car = $4
Final amount at hand = $12
Mathematically ;
x/2 + 4 = 12
x/2 = 12 - 4
x/2 = 8
x = 2 * 8
x = $16
Weekly allowance = $16
$150 (budget) - $30 (spend on herself) = $120 (left)
120 / 15 = $8
(150 - 30) divided by 15 = $8
Only $8 maximum can be spent on each family member
1) 16 X 16= 256
2) 17 x 17 = 289
3) 18 x 18 = 324
4) 19 x 19 = 361
the answer is 2 because it's the largest number that is smaller than 300.
I’m not very good at math, but maybe try adding all of them together
