If gumballs cost 150 a bag ,and there 15!gumballs in each bag much do you need to charge for each gumball in order to make money
pshichka [43]
More than 10 a gumball.

150 divided by 15 is 10, which would be the price you bought for. If you want to make more money, you must at least have a surge pricing of 10 unit prices per gumball.

Tickets to a band concert cost $10 each. The equation y = 10x represents total cost, y, of x tickets. Which graph shows ordered
ser-zykov [4K]

Answer:

the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.

The correct graph is attached below.

Step-by-step explanation:

Given the function equation

  • y = 10x

Given that the cost of each ticket is $10.

It means:

at x = 0, y = 10(0) = 0                ∵ cost of 0 ticket

at x = 1, y = 10(1) = 10                 ∵ cost of 1 ticket

at x = 2, y = 10(2) = 20               ∵ cost of 2 tickets

at x = 3, y = 10(3) = 30                ∵ cost of 3 tickets

at x = 4, y = 10(4) = 40                ∵ cost of 4 tickets

at x = 5, y = 10(5) = 50                 ∵ cost of 5 tickets

Now, observe the ordered pairs points on the right-hand graph of the first diagram.

This graph has the following ordered pairs:

  • (0, 0)     i.e. at x = 0, y = 10(0) = 0
  • (1, 10)     i.e. at x = 1, y = 10(1) = 10          
  • (2, 20)   i.e. at x = 2, y = 10(2) = 20  
  • (3, 30)   i.e. at x = 3, y = 10(3) = 30    
  • (4, 40)   i.e. at x = 4, y = 10(4) = 40  
  • (5, 50)   i.e. at x = 5, y = 10(5) = 50

Thus, the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.

The correct graph is attached below.
