Brenda school is selling tickets to a spring musical on the first day of ticket sales for school so three senior citizen tickets
MrRa [10]

Answer:

senior citizen cost $4

children cost $7

Step-by-step explanation:

The question is not complete

<em>Brenda's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 3 senior citizen tickets and 9 child ... The school took in $67.00 on the second day by selling 8 senior citizen tickets and 5 child tickets. What is the price each of one senior citizen ticket and one child ticket?</em>

Given data

let senior citizens be x

and children be y

so

3x+9y= 75--------------1

on the second day

8x+5y= 67------------2

solve 1 and 2 above

3x+9y= 75     X8

8x+5y= 67      X3

 24x+72y=600

-24x+15y=201

   0x+57y= 399

divide both sides by 57

y= 399/57

y= $7

put y= 7 in eqn 1 above

3x+9*7= 75

3x+63= 75

3x=75-63

3x=12

x= 12/3

x= $4

Write parametric equations of the line 2x-y=3
dangina [55]
In this item we are given with the equation, 2x - y = 3. The equation contains two variables, x and y. We assume in this item that the value of x is independent of the value of y; however, y values depends on the given values of x. In parametric form, the equation would take the form,

    f(x) = y = ax + b

where a is the numerical coefficient of x and b is constant. Transforming the given equation to this form,

   f(x)  = y = 2x - 3

millicent earned $435 last year in interest. If $3000 was invested at a certain rate of return and $4500 was invested in a fund
tatiyna

Answer:

7% and 5%

Step-by-step explanation:

The computation of the two rates of interest is shown below;

The interest  rate for $3,000 be x%

And, for $4,500 the interest rate is (x -2%)

The total interest earned is

= x% of $4,500 + (x - 2)% of $4,500

So, the two rates of interest is

x% of $4,500 + (x - 2)% of $4,500 = $435

30x + 45(x - 2) = $435

30x + 45x - 90 = $43

75x = $25

x = 7%

x - 2 = 7 - 2

= 5%
