Talja [164]

Answer:

The answer to your question is: I bought 7 snacks

Step-by-step explanation:

Data

beginning balance = $42 = b

lunch = $1.80 = l

snack = $ 0.85 = s

final balance = $0.05 = f

f = b - 1.8l - 0.05s

0.05 = 42 - 1.8l - 0.85s

After 20 days I spent = 1.8(20) in lunches = $36

0.05 = 42 - 36 - 0.85s

0.05 = 6 - 0.85s

0.05 - 6 = -0.85s

-5.95 = -0.85s

s = -5.95/-0.85

s = 7

Let x = Darlene's dog's weightlet y = Leah's dog's weight x = 5yx + y = 84 so, 5y + y = 84, which means 6y = 84 so, y = 84/6 = 14x = 5(14) = 70 Darlene's dog = 70 lbs, Leah's dog = 14 lbs.<span> </span>
