Answer:
Yes
With an extra 3000CHF
Step-by-step explanation:
In year 2005, the exchange rate was 1$ = 1.15CHF
The student came in with $20,000.
The amount he had in CHF(swiss franc) = ?
$1 = 1.15C
$20,000 = x CHF
X = (20000 × 1.15) / 1
X = 23,000CHF
When he came to Zürich in 2005, he has 23,000 swiss franc.
But the exchange rates changed in 2006 to C1.30 against the dollar.
$1 = 1.30CHF
$20,000 = xCHF
X = 26,000CHF
In 2006, he would've had 26,000CHF.
The difference between what he would've had in 2006 against 2005 is
26,000CHF - 23,000CHF = 3000CHF
He would've had an extra 3000CHF if he came in the year 2006.
Therefore in order from least to greatest it is 21, 22, and 23

Answer:
15ft by 18ft
Step-by-step explanation:
Start with 2.5 divided by .25
That equals 10
10 times 1.5 ,because we know it takes ten .25inches to equal 2.5 and 2.5, is the size of one of the sides.
10 time 1.5 is 15ft
3 divided by .25 is 12
using the same logic and math as stated above we know 3 x .25 equals 12 by 12 quarter inches to make 3 inches
12 x 1.5 Same logic as before
12 x 1.5 equals 18ft
The kitchen is 15ft by 18ft
