qwelly [4]

<span> f(x)=4x^8+7x^7+1x^6+
</span>∴<span> f(-2)=4(-2)^8+7(-2)^7+1(-2)^6+1
</span>∴ <span>f(-2)=(4x256) + (7x-128) + (1x64) +1
</span>∴ <span>f(-2)=1024 - 896 + 64 +1
</span>∴ <span>f(-2)= 193</span>

ra1l [238]

Answer:

$ 154

Step-by-step explanation

Let the value of suitcase=x

x × 4.5% = 6.93 (converted the question into equation)

x × $\frac{4.5}{100}$ = 6.93 (converted the percentage into fraction)

x = 6.93 x $\frac{100}{4.5}$ (took reciprocal of 4.5/100 after moving it to the other side of the equation)

x = $\frac{693}{4.5}$ (multiplied the values)

x = 154 $ (simplified the fraction)
