Brianna wants to buy a digital camera for a photography class. one store offers the camera for $50 down and a payment plan of $20 per month. the payment plan for a second store is described by y 15x + 80, where y is the total cost in dollars and x is the number of months. which camera is cheaper when the camera is paid off in 12 months? explain.

The second camera. The second camera is $30 cheaper than the first camera.

Step-by-step explanation:

The equation of the first store is y = 20x + 50. Keep this in mind.

Replace x with 12 in each of these equations to determine which is cheaper.

y = 20(12) + 50 = $290

y = 15(12) + 80 = $260

So the second store is cheaper.

$12. that is my answer.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
