HELP please I’ll make u the brainiest if right
The equation y = 1.55x + 110,419 approximates the total cost, in dollars, of raising a child in the United States from birth to 17
years, given the household's annual income, X.
Approximately how much would it cost to raise a child in a household with an annual income of $84,400?
$130,820
$168,242
$210,386
$241,239

D is your answer

Step-by-step explanation:

All you have to do is just input the numbers into the equation.

y=1.55(84400)+110419

y=130820+110419

$241,239

So, D is your answer.

Hope this helps!

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
