verykiasummy & SarCha,
1 - 2/5 = 3/5 (remainder)
3/5 x $480 = $288
1 - 1/4 = 3/4 (spent on 4 blouses)
3/4 x $288 = $216 (4 blouses)
$216 / 4 = $54 (each blouse)
ans : $54
Many thanks for your help!

Ray and Serene have a total of $1183 in their savings accounts. Serene and Tim have a total of $1124 while Ray and Tim have a total of $961.
How much savings does Tim have?
S+T = 1124 ---------- (2)
R+T =961 ------------- (3)
Add 2 and 3
R+S+2T = 2085
Compare the new equation to 1
1183+2T = 2085
2T = 902
T = 401 -
Thank you, CNS!

Here’s another one:-
A class has an equal number of boys and girls. ½ of the boys do not wear glasses and 15 girls do not wear glasses. 12 of the pupils wear glasses. How many pupils are there in the class? -

Is the answer 36 ? If so, below is the working :Here's another one:-
A class has an equal number of boys and girls. ½ of the boys do not wear glasses and 15 girls do not wear glasses. 12 of the pupils wear glasses. How many pupils are there in the class?
U + [] = 12
[] + 15 = 2U
[] = 2U - 15
Substituting the 3rd equation into the first, you would get :
U + 2U - 15 = 12
3U = 27
U = 9
Boys + girls add up to 4U -
Thank you, CNS…you’re great!

No issue. Tell you something. I seem to derive more satisfaction solving maths now than to teach my own child. Her \" care-less\" attitude is driving me mad
