mamaluj [8]

Answer:

$33

Step-by-step explanation:

c = price of cheese; s = price of sausage

3c + 3s = $36

s = c - 2

3c + 3(c - 2) = 36

2c - 2 = 12

c = $ 7

s = 7 - 2 = $ 5

Therefore, price of 4 lb of cheese and 1 lb of sausage is 4c + 1s = $28 + $5 = $33

Function,d(r) = 0.034r , is used to convert Russian rubles in United States dollars, and function, e(d) = 0.76d , is used to con

Dahasolnce [82]

We have two functions, one which converts rubles to USD and one which converts USD to euros. If we want to convert from rubles to euros, we could just convert it to USD and then euroes.

2000₽ ⇒ USD
$d(r)=0.034r\\d(2000)=0.034(2000)=68$

$68 USD ⇒ €
$e(d)=0.76d\\e(68)=0.76(68)=\boxed{51.68}$

Extra: If you wanted, you could create a function to convert rubles into euroes.
Just substitute that 0.034r for d in e(d) = 0.76d and... $e(r)=0.76(0.034r)=0.02584r$
