Answer:
6+33 and 3(2)+3(11) are the correct answers.
Step-by-step explanation:
Sum of the geometric sequence:
S n = a * ( 1- r^n ) / ( 1 - r )
a = - 4 ( the 1st term of the sequence ), r = - 6, n = 7
S 7 = (- 4 ) * ( 1 - ( - 6 )^7 ) / 1 - ( - 6 ) = ( - 4 ) * 279937 / 7 = - 159,964
Answer: B )
Answer:
The amusement park needs to pay at least $98.40 to 225 employees. So the minimum price they need to charge to pay all the employees is 98.40 x 225
Step-by-step explanation:
Profit minimum= employee pay x employee amount
98.40 x 225
After multiplication, profit minimum needs to be= $22140
Divide profit minimum by guests to get price per ticket
22140/1000 guests
$22.14= price of ticket for minimum profit

Answer: the total cost for an order of 20 copies is $13.9
Step-by-step explanation:
Let x represent the number of copies ordered.
The printing service charges a set-up fee of $12.50 for each order and 7 cents more for each copy.
The equation representing the total cost, C (in dollars), for an order of x copies is expressed as
C = 0.07x + 12.50
Therefore, the total cost for an order of 20 copies would be
C = 0.07 × 20 + 12.5
C = 1.4 + 12.5
C = 13.9 dollars
