If total sales are $54,000 and your food service total is 42% of your total sales, what is your dollar target for food service?

$22,680.

Step-by-step explanation:

It is given in the question that total sales are = $54,000

your food service is 42% of your total sales = 42% × $54,000

= × 54,000

= 0.42 × 54,000

= $22,680

Your dollar target for food service is $22,680.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
