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:
5/8 - (1/4)^2 = 0.5625, hope this helps!

<u>Step 1: Define</u>
<em>Identify</em>
a⁴ - 6b + 3b ÷ ac
<em>a</em> = -2
<em>b</em> = 6
<em>c</em> = 3
<u>Step 2: Evaluate</u>
- Substitute in variables: (-2)⁴ - 6(6) + 3(6) ÷ (-2)(3)
- Exponents: 16 - 6(6) + 3(6) ÷ (-2)(3)
- Multiply: 16 - 36 + 18 ÷ (-2)(3)
- Divide: 16 - 36 - 9(3)
- Multiply: 16 - 36 - 27
- Subtract: -47
