let x = orginal price of the shorts

$21 = x(100%-20%) * 1.05

$21 = x(80%) * 1.05

$21 = 0.8x * 1.05

Subtract 1.05 from both sides

$19.95 = 0.8x

Divide 0.8 from both sides

$24.9375 = x

So the orginal price of the shorts are about $24.94

andrezito [222]

Answer:

To complete the required $m dollars for her college, she needs $(m - 60,000).

Step-by-step explanation:

Suppose Rebecca needs $m to complete her college education,

because she has a yearly scholarship of $10,000, she would have $10,000 × 4 = $40,000 for the four years she would spend in college.

Together with her savings of $20,000, she has $20,000 + $40,000 = $60,000 in total.

Therefore to complete the required $m dollars for her college, she needs $(m - 60,000).

The parents of three children, ages 1, 3, and 6, wish to set up a trust fund that will pay X to each child upon attainment of ag

ehidna [41]

Answer:

The equation of <em>Z</em> is: $Z=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})$

Step-by-step explanation:

The first child is of age 1 year.

Then the amount invested for the 1-year old is: $Xv^{17}+Yv^{20}$

The second child is of age 3 years.

Then the amount invested for the 3-year old is: $Xv^{15}+Yv^{18}$

The third child is of age 6 years.

Then the amount invested for the 6-year old is: $Xv^{12}+Yv^{15}$

The one-time investment will be:

$Z=Xv^{17}+Yv^{20}+Xv^{15}+Yv^{18}+Xv^{12}+Yv^{15}\\=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})$
