The net amount they raise is the amount they receive minus what they pay in expenses.

They receive:
$10,000 fixed amount in donations
$55 per person

They pay:
$15 per person

If there are x number of entries, they receive 55x from the entries.
Also, they pay 15x for the entries.

The net amount they raise is amount they receive min us amount they pay:

55x + 10,000 - 15x

which simplifies to

40x + 10,0000

They want to raise at least $55,000.
At least $55,000 means $55,000 or more.
They want to raise an amount greater than or equal to $55,000.

Now we write the inequality:

40x + 10,000 >= 55,000

Now we solve the inequality for x, the number of entries.

40x >= 45,000

x >= 1125

They must have 1125 or more race entries to raise $55,000.

Shopping at clothing world, jenna buys her children four shirts and three pairs of pants for 124.25. She returns the next day an
Aleksandr-060686 [28]

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

Step-by-step explanation:

Let,

Cost of one shirt = x

Cost of pair of jeans = y

According to given statement;

4x+3y=124.25    Eqn 1

3x+5y=161.25     Eqn 2

Multiplying Eqn 1 by 3

3(4x+3y=124.25)\\12x+9y=372.75\ \ \ Eqn\ 3

Multiplying Eqn 2 by 4

4(3x+5y=161.25)\\12x+20y=645\ \ \ Eqn\ 4

Subtracting Eqn 3 from Eqn 4

(12x+20y)-(12x+9y)=645-372.75\\12x+20y-12x-9y=272.25\\11y=272.25

Dividing both sides by 11

\frac{11y}{11}=\frac{272.25}{11}\\y=24.75

Putting 24.75 in Eqn 1

4x+3(24.75)=124.25\\4x+74.25=124.25\\4x=124.25-74.25\\4x=50

Dividing both sides by 4

\frac{4x}{4}=\frac{50}{4}\\x=12.50

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

(x +y) + Z commutative property of addition
goldenfox [79]

Answer:

Step-by-step explanation:

commutative property of addition :  x + y = y + x

example : 2+3 =5 and 3+2 =5 then 2+3=3+2

associative property of addition

x + y + z = (x + y) + z = x + (y + z)

example: 2+3+4 = (2+3)+4 = 5 + 4 =9

               2+3+4 = 2+(3+4) = 2 + 7 = 9
