Answer:
The compound interest one is better by about 14 bucks.
Step-by-step explanation:
Simple interest:
500(1+.06*10)=800
Compound interest:
500(1+.05)¹⁰=814.45
X+x+2= 56 2x=54 The answer is 27 and 29
Divide 1500 by 1000
1500/1000 = 1.5
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
