Answer/Step-by-step explanation:

Plug in each given value of T in the formula for speed of sound, s, that is given as s = 20\sqrt{273 + T}

22. 0°C

s = 20\sqrt{273 + 0}

s = 20\sqrt{273}

s = 20*16.5 = 330 m/s

23. 20°C

s = 20\sqrt{273 + 20}

s = 20\sqrt{293}

s = 20*17.1 = 342 m/s

24. -10°C

s = 20\sqrt{273 +(-10)}

s = 20\sqrt{273 - 10}

s = 20\sqrt{263}

s = 20*16.2 = 324 m/s

25. 70°C

s = 20\sqrt{273 + 70}

s = 20\sqrt{343}

s = 20*18.5 = 370 m/s

The dryer costs 425 dollars

Step-by-step explanation:

x - washer

y - dryer

x+y=774

x=y-76

(y-76)+y=774

2y=774+76, 2y=850

y=425

y-76=x

425-76=x

x=349
