Ivahew [28]

Answer:

Job A pay <u>$25</u> than Job B.

Step-by-step explanation:

Given:

Job A -Sales- offers a base salary of $1,000 per week plus 3% commission on all sales above $3000.

Job B -Sales- offers a base salary of $1,100 per week plus 2.5% commission on all sales above $3000.

The total sales for the week equal $25,000.

Now, to find how much more money Job A pay than Job B.

Total sales = $25,000.

Job A pay:

Base salary = $1,000.

Base salary plus 3% commission on $25000.

$1000 + 3% of $25000.

= $1000+\frac{3}{100}\times 25000$

$=1000+0.03\times 25000$

$=1000+750$

$=1750.$

Job A pay = $1750.

Now,

Job B pay:

Base salary = $1,100.

Base salary plus 2.5% commission on $25000.

$1,100 + 2.5% of $25,000.

$=1100+\frac{2.5}{100}\times 25000$

$=1100+0.025\times 25000$

$=1100+625$

$=1725$

Job B pay = $1725

So, by deducting the salary of Job B from Job A we get the more amount:

$1750-1725\\=25$

Therefore, Job A pay $25 than Job B.

algol [13]

Answer: Inequality

Step-by-step explanation:

From the question, if we can describe 15×-10 as an expression, then we would describe 6×-2< 35 as an inequality. An

inequality is used to compare two values, and shows if one is less than, or greater than, or maybe not equal to the other value.

For example, a ≠ b means that a is not equal to b and a < b means a is less than b while a > b means a is greater than b. From the question, 6×-2< 35 means that 6x - 2 is less than 35.
