Suppose you buy a phone for $200 and its value depreciates linearly. If the phone is worth $115 after four years, then what is t

vredina [299]

Answer:

$72.5

Step-by-step explanation:

Initial value = $200
Depreciated value after 4 years = $115

Since depreciation rate is linear, then:

200 - 4x = 115
4x = 200 - 115
4x = 85
x = 85/4
x = 21.25

Value after 6 years:

200 - 6*21.25 = 200 - 127.5 = $72.5

Rico spent $87.00 to go to the movies on Friday night. He spent $25.75 on popcorn and drinks and paid $12.25 for each movie tick

Svetlanka [38]

You haven't given the equations I'm supposed to chose from, but the answer would be

25.72 + 12.25x = 87.00 is the equation.

He spent a total of $87

The popcorn was 25.75 and each ticket was 12.25, which means we must add the amounts they costs and multiply how my tickets he bought, which is x.

5 is the solution
