Mathematics
1 answer:
Vladimir79 [104]3 years ago
5 0

Answer:

0.25

Step-by-step explanation:

we have

(-0.5)^2

we know that

-0.5=-\frac{1}{2}

substitute

(-\frac{1}{2})^2=(-\frac{1}{2})(-\frac{1}{2})

Remember that

(-1)(-1)=1\\(-1)(1)=(-1)

so

(-\frac{1}{2})(-\frac{1}{2})=\frac{1}{4}=0.25

Given :

Greg earns a salary of $300 per week plus an additional  6% commission on his sales.

To Find :

If his weekly salary  increases by $50 and his commission increases to 7%  how much will Greg earn if his weekly sales are  $4,000.

New commission on $4000 sales :

C=\dfrac{4000\times 7}{100}= \$280 .

Therefore, total earning T = S + C = $( 350 + 280 ) = $630 .

Hence, this is the required solution.
