A function C(x) = 8x + 15 represents the cost C. in dollars of producing x, T-shirts for
the marching band.
what would be the cost of producing 60 t shirts?
find the number of t shirts if c(x)=303
Answer:
The cost of producing 60 t-shirts is $495.
36 t-shirts will let the cost, C(x) = 303
Step-by-step explanation:
If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.
C(x) = 8x + 15
C(x) = 8(60) + 15
C(x) = 480 + 15
C(x) = 495
If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).
C(x) = 8x + 15
303 = 8x + 15
288 = 8x
x = 36

There are 100 coins with a total value of $10.15. How many quarters do you have? How many dimes do you have?
9514 1404 393
Answer:
99 dimes1 quarterStep-by-step explanation:
If all 100 coins were dimes, the value would be $10.00. Each dime traded for a quarter adds $0.15 to the value.
The actual value of the coins is $10.15 -10.00 = $0.15 more than it would be for all dimes. This indicates 1 dime has been traded for a quarter.
There are 99 times and 1 quarter.

An initial deposit of $1,000 is made into a savings account that is compounded continuously at 3% interest. How much money will be in the account after 18 years?
Answer:
$1700
Step-by-step explanation:
Given data
Principal P=$1000
Rate r= 3%
Time T= 18years
Required
The final amount A
The expression for the compound interest is
A= P(1+r)^t
substitute
A=1000(1+0.03)^18
A=1000(1.03)^18
A= 1000*1.70
A=$1700
Hence the final amount after 18 years is $1700

What do I do plz help
Answer:
x = 54°
Step-by-step explanation:
90° = 2x-18°
90° + 18° = 2x
108° = 2x
x = 54°
Answer:
x = 54
Step-by-step explanation:
The two angles added together equal 90 degrees because they are complementary angles.
x - 18 + x = 90
Combine like terms
2x - 18 = 90
add 18 to both sides
2x = 108
Divide each side by 2
x = 54
Fill in for x
54 - 18 + 54 = 90
36 + 54 = 90
90 = 90
This proves that the answer is true.

Answer:
x = 8
Step-by-step explanation:
The marked angles are alternate interior angles, so are congruent.
8x -4 = 60
8x = 64 . . . . . . . . . . add 4 to both sides
x = 64/8 = 8 . . . . . . divide both sides by 8
The value of x is 8.
