Answer:

V = 10a^3+91a^2+54a-792

Step-by-step explanation:

V = (2a+11) (5a-12) (a+6)

V = (10a^2-24a+55a-132)(a+6)

V = (10a^2+31a-132)(a+6)

V = (10a^3+60a^2+31a^2+186a-132a-792)

V = 10a^3+91a^2+54a-792

Mary earns $28,000 a year plus commission. One week she grossed $655.58. She had sold $1673.19 worth of merchandise. What is the
insens350 [35]

Answer:

Step-by-step explanation:

The parameters given are;

The amount Mary earns annually = $28,000

The amount Mary grossed during a week = $655.58

The amount Mary had sold during the week to make the amount grossed during the week = $1673.19

Given that Mary makes $28,000 per year

Therefore;

The amount Mary earns per week = Amount earned per year/52

The amount Mary earns per week =  $28,000/52 = $538.46

The amount extra she made on commission = $655.58- $538.46= 1$117.12

The commission rate = Commission earned/(Amount of merchandise sold)×100

The commission rate = 117.12/1673.19 × 100 = 6.99%

Her commission rate = 6.99%

Capucine played a game where she earned 179 points from building 11 museums and 4 libraries. She earns 4 more points per museum
Korolek [52]

Capucine played a game where she earned 179 points from building 11 museums and 4 libraries.

Lets assume  x points she earn per library

She earns 4 more points  for museum than  library.

4 more points per museum per x .  so the points earned per museum is x+4

she earned 179 points from 11 museums and 4 libraries.

So the equation becomes

11 (x+4) + 4x = 179

11x +44 + 4x = 179

15x + 44 = 179 ( subtract 44 from both sides)

15x= 135 (divide by 15 from both sides)

x = 9

She earns 9 points per library

We know points per museum = x+4 = 9+4 = 13

She earns 13 points per museum .
