Answer:
25%
Step-by-step explanation:
Apparently, we're to assume that anything not spent is saved.
Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...
Akira's expenses = (3/5)(5/8) = 3/8 . . . . . of Hideo's income
Hideo's expenses are twice this amount, so ...
Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income
That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.
Hideo saves 25% of his income.

Answer:
y = $30x ;
1 : $30
Step-by-step explanation:
Given that :
$60 is saved in electricity bill for every 2 panels
Model, y
Amount saved, y = amount saved per panel * number of panels
Let number of panels = x
Hence, total amount saved, y ;
y = $30x
Ratio of panels to money saved :
Number of panels : amount of money saved
2 : $60
1 : $30
Hence, $30 is saved in cost of electricity bill per 1 solar panel purchased.
