Alan is a software salesman. His base salary is $1600, and he makes an additional $40 for every copy of Math is Fun he sells. Let P represent his total pay (in dollars), and let N represent the number of copies of Math is Fun he sells. Write an equation relating P to N. Then use this equation to find his total pay if he sells 21 copies of Math is Fun. Equation: D=0 Total pay if Alan sells 21 coples: $] Х 5 ?

use this formula:

p(a\b) = p(a and b)/p(b).

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
