The correct question is
The local currency it gives is a total of 275 Yuan. <span>If the yuan is worth 6.58 to a US$, what would the price to a US$ be if the yuan changed to 6.25
The </span><span>options are A)$2.21 B)$2.50 C)$13.31 D)$41.79 E)$44.00
we know that
</span><span>at the current exchange rate give (6.58)
</span>if 1 usd-----------------> 6.58 yuan
X usd------------------> 275 yuan
X=275/6.58------------> X=41.79 usd
at the current exchange rate give (6.25)
if 1 usd-----------------> 6.25 yuan
X usd------------------> 275 yuan
X=275/6.25------------> X=44 usd
so
the change in price in US$ would be [44-41.79]=US$2.21

Answer:
b = -1/10.
Step-by-step explanation:
(2i/2+i)-(3i/3+i)
= 2i(3 + i) - 3i(2 + i) / (2 + i)(3 + i)
= 6i + 2i^2 - 6i - 3i^2 / (2 + i)(3 + i)
= (-2 + 3) / (6 + 5i - 1)
= 1 / (5 + 5i)
Now we multiply top and bottom by 5 - 5i :
= 5 - 5i / (5 + 5i)(5 - 5i)
= 5 - 5i / 25 -25i^2
= 5 - 5i / 50
= 1/10 - 1/10i
