We are given expression for cost of admission at an amusement park : 15a+12c.

Where a is the number of adults and

c is the number of children.

We need to find the total cost of 5 adults and for 10 children.

<em>In order to find the total cost of 5 adults and for 10 children, we need to plug a=5 and c=10 in 15a+12c expression.</em>

Plugging a=5 and c=10 in 15a+12c expression, we get

15(5) + 12(10) = 75 + 120 = $195.

<h3>Therefore, the total cost for 5 adults and for 10 children is $195.</h3>

Alisiya [41]

Answer:

The expression to determine the total cost in dollars is y=25+0.75x.

Step-by-step explanation:

Given:

Service charge to make a photo book = $20

Cost per extra page = $0.75

Cost to ship the complete photo book = $5

We need to write expression to determine the total cost in dollars.

Solution:

Let the number of extra pages be denoted by 'x'.

Also Let the Total cost be denoted by 'y'.

Now we can say that;

Total cost will be equal to sum of Service charge to make a photo book and  Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.

framing in equation form we get;

y=20+0.75x+5\\\\y=25+0.75x

Hence the expression to determine the total cost in dollars is y=25+0.75x.

Find equation of vertical line through (-5, -3)
Novay_Z [31]

Answer:

x = -5

Step-by-step explanation:

Given that it is a vertical line, we know that it will only go through one x-value.

We are also given a point, (-5, -3).

This point tells us that the vertical line only goes through the x-value -5, so the equation will be x = -5.

Vesna [10]

Answer:

A:4000

B:2000

C: More interest on the 4 year loan

Step-by-step explanation:

5% of 20000 is 1000 so the amount of years times the amount of interest per year. 4 years is (4x1000=4000) and 2 years is (2x1000) 4000 is greater than 2000.

if this is incorrect it is using rising interests just let me know and ill edit

Xavier c. wants to purchase a machine for $37,000 with a four year life and $1,000 salvage value. Xavier requires an 8% return o
tangare [24]
(a) Net present value of machine
Pm=-C+V/(1+i)^n=37000-1000/1.08^4
=-36264.97
=-36265 (rounded to nearest dollar)

Cost of machine amortized over 4 years (annualized cost)
Ac=Pm(A/P,i,n)=-36264.97(A/P,0.08,4)=-36264.97(.08*(1.08^4)/(1.08^4-1)
=-10949.15

Expected year-end cash flow = annualized return - annualized cost  =>
12000=return - 10949.15

(b) Internal rate of return of machine
=return/cost - 1
=(12000-(-10949.15)/10949.15-1
=2.096-1
=1.096
=109.6%
