Answer:
The money which Mrs. Walker saves each week is $ 65 .
Step-by-step explanation:
Given as :
The part of money which Mrs. walker saves from part time job = [tex]\frac{1}{3}[/tex] of her total earning
The value of [tex]\frac{2}{5}[/tex] part of her salary = $ 78.00
Let The total earning from part time job = $ x
So, The value of [tex]\frac{2}{5}[/tex] of total earning = $ 78.00
Or, [tex]\frac{2}{5}[/tex] × x = 78.00
Or, x = [tex]\frac{78\times 5}{2}[/tex]
∴ x = 39 × 5
I.e x = 195
So, her total earning from part time job = x = $ 195
Now ∵ The part of money which Mrs. walker saves from part time job = [tex]\frac{1}{3}[/tex] of her total earning
So, The part of money which Mrs. walker saves from part time job = [tex]\frac{1}{3}[/tex] × 195
Or, The part of money which Mrs. walker saves from part time job = [tex]\frac{195}{3}[/tex]
∴ The part of money which Mrs. walker saves from part time job = $ 65
Hence The money which Mrs. Walker saves each week is $ 65 . Answer
