Answer:
b=4
Step-by-step explanation:
1 1/5 x 5 3/5 is 3 3/5. Hope this helps!
First, we must let:
x = number of tickets intended for adults
y = number of tickets intended for children.
a. Write in terms of x the number of tickets for children
Solution:
x + y = 28 ⇔ y = 28 - x (equation 1)
To answer in terms of x:
no. of tickets for tickets for children = 28 - x
b. the amount spent on tickets for adults
Solution: $30 is the cost of ticket per adult and there are x number of tickets intended for adults.
Therefore,
amount spent on ticket for adults = 30x
c. the amount spent on the tickets.
Solution:
$ 15 = cost of ticket per child
$ 30 = cost of ticket per adult
total amount spent on tickets = 30x + 15y ⇒ (equation2)
substitute equation 1 to equation 2.
(equation 1) y = 28 - x
(equation 2) total amount spent on tickets = 30x + 15y
total amount spent on tickets = 30x + 15(28-x)
total amount spent on tickets = 30x + 420 - 15x
total amount spent on tickets = 15x + 420
Answer:
Increase?
Step-by-step explanation:
Because think about it let's use 1/2 as an example.
1/2 equals .5 now lets add 2 to both the numerator and denominator
3/4 is the result and it also equals .75 which is larger than .5 so that's why the answer is increase.
and u can keep on going on with the method
4/5=.8
