Answer:
5%
Step-by-step explanation:
22.05-21=1.05
1.05/21=.05
.05*100=5%
Answer:
a. 9.5x + 6.5(x+c) < 8 when c>0
b. Must be one child more than the no. of adults.
Step-by-step explanation:
For Cinema 1:
for adult = $9.50
for child = $6.50
For Cinema 2:
Per person regardless of age = $8.00
First of all, we will find out the condition when per person rates in both cinema are equal.
Assume x = no. of adults
y = no. of children
Rate per person in Cinema I = Rate per person in Cinema II
(9.5x + 6.5y)/(x+y) = 8
9.5x + 6.5y = 8(x+y)
9.5x + 6.5y = 8x + 8y
9.5x-8x = 8y-6.5y
=> x = y
So rates are equal when no. of adults equals no. of children
For Cinema I to have better rates, no. of children should be atleast 1 more than the no. of adult. In this way the rate per person of Cinema I will be less than 8
Hence we form an inequality when y = x+c and c > 0
9.5x + 6.5(x+c) < 8 when c>0
Hence there must be 1 more children than the no. of adults attending Cinema I for it to be a better deal.
Answer:
a*sqrt(x+b) + c = d
or
a*√(x+b) + c = d

Answer: 236 kcal
Step-by-step explanation:
Given : A serving of fish contains 50 g protein and 4 g of fat.
i.e. content of protein = 50 g
content of fat = 4 g
Also, The caloric value in protein = 4 kcal/g
The caloric value in fat = 9 kcal/g
Calories in 50 g protein = (content of protein)x (caloric value in protein )
= 50g x 4 kcal/g = 200 kcal
Calories in 4 g fat= (content of fat)x (caloric value in fat)
=4 g x 9 kcal/g = 36 kcal
Then, the total calories in the serving will be :Calories in 50 g protein + Calories in 4 g fat
= 200 kcal+ 36 kcal =236 kcal
Hence, there are 236 kcal in the serving.
5x4=the amount of change. His total change was $20
