S+d=209
d=209-s
6.5s+2d=836.5
6.5s+2(209-s)=836.5
6.5s+418-2s=836.5
4.5s+418=836.5
4.5s=418.5
s=93

There were 93 salads sold that day.

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Whenever she began to drive farther east, at 70 km per hour, Prachi was 5 km east of her home.

Let f(n) at the beginning of her nth hour drive be Prachi's distance to her home.

f is a sequence of arithmetic.

Write a series explicit form.

$\to f(n) = 70n + 5$

The graph of function g is a vertical stretch of the graph of function f by a factor of 3.

Assoli18 [71]

Question says that the graph of function g is a vertical stretch of the graph of function f by a factor of 3.

Now we have to find about which equation describes function g.

We know that if f(x) is the given function then a*f(x) gives vertical stretch or compress by a factor of a.

when 0<a<1 then it compresses by factor of a.

when a>1 then it stretches vertically by factor of a.

Given that function f is stretched by a factor of a so that means we use a=3 in formula a*f(x)

Hence final answer will be g(x)=3f(x).

So choice A is correct answer.
