DIA [1.3K]

Answer:

<em>Option C</em>

Step-by-step explanation:

If we were to consider this question as a whole, all we are being asked is to find an expression equivalent to 2 * ( 5 )^x, as all other function are expressed in the same f ( x ) format. Now all we have to thing about are the expression that = 2 * ( 5 )^2x;

$2( 5 )^2x =\\2( 5^2 )^x =\\2( 25 )^x\\\\Solution - Option C$

Sam is paid $14 per hour plus 6% of sales. If he worked 37.5 hours in one week, what would his sales need to be for him to make

Ulleksa [173]

Answer:

Step-by-step explanation

Let the sales be represented by x

Amount made from no of hours worked = $14 × 37.5 hours=$525

Sales made = 6% of x=0.06x

Total = 0.06x+$525=$733.50

0.06x=733.50-$525=$208.5

x=$3,475
