p(b) =  \frac{5}{16}

p(g |without \: replacement|) =  \frac{3}{16 - 1}  =  \frac{3}{15}  =  \frac{1}{5}  \\

p(b \: and \: g) =  \frac{5}{16}  \times  \frac{1}{5}  =  \frac{1}{16}

Steven just got a new summer job painting fences in his neighborhood. He will be paid $7.25 an hour. His first customer paid him
mote1985 [20]

Answer:

a). The equation; 7.25 h-36.25=0

b). total number of hours Steven work=5 hours

Step-by-step explanation:

Part A

The expression for the total money earned is as follows;

T=E×h

where;

T=total earnings

E=earnings per hour

h=number of hours worked

In our case;

T=$36.25

E=$7.25

h=h

replacing;

36.25=(7.25×h)

36.25=7.25 h

The equation would be; 7.25 h=36.25, or 7.25 h-36.25=0

Part B

7.25 h=36.25

h=36.25/7.25

h=5

total number of hours Steven work=5 hours
