Step-by-step explanation:
(a)
= 1 ( any value divided by itself = 1 )
(b)

(c)
×
= 
The product of 2 fractions is the product of the numerators divided by the product of the denominators
(d)
÷
= 
To divide 2 fractions, leave the first fraction, change division to multiplication and turn the second fraction upside down, that is
÷
=
×
= 
(e)
+
= 
Since the fractions have a like denominator, add the numerators leaving the denominator. This applies to subtraction also
(f)
-
=

Step-by-step explanation:
240.70×4=962.8 (for return)
569×4=2240 (hotel cost)

I imputed the equation in my calculator
Answer:
r= −100c+100d/ct
Step-by-step explanation:
d=c(1+rt/100)
1/100crt+c=d
1/100crt+c+−c=d+−c
1/100crt=−c+d
= 
Solve 10x = 4.1 for x. Divide both sides of this equation by 10: x = 4.1 / 10.
x = 0.41
