Answer:

Part One: $187

Part Two: 11a + 5.5k

Step-by-step explanation:

Part One:

a = 9 (how many adult tickets)

k = 16 (how many kid tickets)

($11 × a) + ($5.50 × k) = total cost

($11 × 9) + ($5.50 × 16)

($99) + ($88) = $187 = total cost

Part Two:

11a + 5.5k

11 is how much the adult ticket costs, you multiply a or the amount of adult tickets in order to get the total cost for adults.

5.5 is how much the kid ticket costs, you multiply k or the amount of kid tickets in order to get the total cost for kids.

you add 11a + 5.5k or the total cost for adults and the total cost for kids to get the total cost.

kap26 [50]

Answer:

-60% decrease

Step-by-step explanation:

60 is the old value and 24 is the new value.

percent change = $\frac{new - old}{|old|}$ x 100%

so for this problem, you can substitute the values given in the formula:

percent change = $\frac{60-24}{|60|}$ x 100% = $\frac{-36}{60}$ x 100% =

-60% (decrease)

ms. jeffers is splitting $775 among her three sons. of the oldest gets twice as much as the youngest and the middle son gets $35

Angelina_Jolie [31]

The oldest son will get $370, the middle will get $220 and the youngest will get $185.

Step-by-step explanation:

Given,

Total amount to be split = $775

Let,

Oldest son's share = x

Middle son's share = y

Youngest son's share = z

According to given statement;

x+y+z=775 Eqn 1

the oldest gets twice as much as the youngest

x = 2z Eqn 2

the middle son gets $35 more than the youngest

y = z+35 Eqn 3

Putting value of x and y from Eqn 2 and 3 in Eqn 1

$2z+(z+35)+z=775\\2z+z+35+z=775\\4z=775-35\\4z=740\\$

Dividing both sides by 4

$\frac{4z}{4}=\frac{740}{4}\\z=185$

Putting z=185 in Eqn 2

$x=2(185)\\x=370$

Putting z=185 in Eqn 3

$y=185+35\\y=220$

The oldest son will get $370, the middle will get $220 and the youngest will get $185.
