Algebra 1 Word Problem

Answer 1

Answer:

otterbox costs $95; beats costs $210

Step-by-step explanation:

x = otterbox   y = beats

4x + 2y = 800      y = 2x + 20

4x + 2(2x + 20) = 800

4x + 4x +40 = 800

8x + 40 = 800

8x = 800 - 40

8x = 760

x = 760 / 8

x = 95  Otterbox costs $95 each

4x + 2y = 800

4(95) + 2y = 800

380 + 2y = 800

2y = 800 - 380

2y = 420

y = 420 / 2

y = 210   Beats costs $210

4(95) + 2(210) = 800

380 + 420 = 800

Answer 2

Answer:

Otterbox = $95

Beats = $210

Step-by-step explanation:

Let's take o for Otterbox and b for Beats.

4 o + 2 b = $800

b = 2 o +$20

So,  4 o + 2 b = $800 => 8 o + $40  = $800

Therefore,

Otterbox = $95

Beats = $210
