Concept explainers

Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

Answer to Problem 15IP

Total Income of Anna is $(5.5x+12)

Explanation of Solution

Given:

Anna and Cole each earn x cents per news paper that they deliver, plus tips. Anna delivered 55 news papers and earned $12 in tips. Cole delivered 68 newspapers and earned $15 in tips.

Concept Used:

Rule: 1  cent  =  $ 0.01  ⇒  x cents  =  $0.0x

Calculation:

Anna delivered 55 news papers and earned $12 in tips.

Anna earn x cents per news paper that they deliver,

Income from 55 newspaper = 55  ·  0.0x  =  $5.5x

Amount of Tips = $12.

Total Income of Anna = $(5.5x+12)

Thus, total Income of Anna is $(5.5x+12)

Answer to Problem 15IP

Thetotal Income of Cole is $(6.8x+15)

Explanation of Solution

Given:

Anna and Cole each earn x cents per news paper that they deliver, plus tips. Anna delivered 55 news papers and earned $12 in tips. Cole delivered 68 newspapers and earned $15 in tips.

Concept Used:

Rule: 1  cent  =  $ 0.01  ⇒  x cents  =  $0.0x

Calculation:

Cole delivered 68 news papers and earned $15 in tips.

Cole earn x cents per news paper that they deliver,

Income from 68 newspaper = 68  ·  0.0x  =  $6.8x

Amount of Tips = $15

Total Income of Cole = $(6.8x+15)

Thus, total Income of Cole is $(6.8x+15)

(c)

To determine

Answer to Problem 15IP

Their total income is $(12.3x+27)

Explanation of Solution

Given:

Anna and Cole each earn x cents per news paper that they deliver, plus tips. Anna delivered 55 news papers and earned $12 in tips. Cole delivered 68 newspapers and earned $15 in tips.

Concept Used:

Total Income of Anna is $(5.5x+12)

Thetotal Income of Cole is $(6.8x+15)

Calculation:

Total Income of Anna is $(5.5x+12)

Thetotal Income of Cole is $(6.8x+15)

Their total income:

  $(5.5x+12)+$(6.8x+15)=$[(5.5x+6.8x)+(12+15)]=$(12.3x+27)

Thus, their total income is $(12.3x+27)
