A restaurant sees about 600 orders on Tuesday. This is down from last Tuesday by about 0.85%. How many did they see last Tuesday

zaharov [31]

Answer:

Number of orders seen on last Tuesday = 605

Step-by-step explanation:

Number of orders seen on Tuesday = 600

It is given that it is 0.85% less than last Tuesday.

Let number of sales on last Tuesday = $x$

As per question statement:

Number of order on last Tuesday - 0.85% of Number of order on last Tuesday = 600

i.e. if we subtract 0.85% of x from x, it must be equal to 600.

$x-\dfrac{0.85}{100}x =600\\\Rightarrow x-\dfrac{0.85}{100}x =600\\\Rightarrow \dfrac{100-0.85}{100}x =600\\\Rightarrow \dfrac{99.15}{100} \times x =600\\\Rightarrow x =\dfrac{600\times 100}{99.15}\\\Rightarrow x =\dfrac{60000}{99.15}\\\Rightarrow x \approx 605$

So, there were about 605 order seen last Tuesday.

Evaluate the function f(x)=4*7^x for x=-1 and x=2. Show your work!

user100 [1]

With this function you are given 2 x's and all we have to do is plug those X's into the function so

f(-1)=4*7^-1

7^-1 is 1/7
times 4 = 4/7

f(2)=4*7^2
7^2=49 *4 = 196
