We are to buy quantities of two items: n1 units of item 1 and n2 units of item 2. An isocost equation shows the relationship between the number of units of each of the two items to be purchased when the total purchase price is predetermined. If the total purchase price is predetermined to be C = 155 dollars, and item 1 costs $5.87 per unit and item 2 costs $3.61 per unit, find the isocost equation for items 1 and 2.
a. 5.87n1 - 3.61n2 = 155
b. 3.61n1 + 5.87n2 = 155
c. (5.87 + 3.61)(n1 + n2) = 155
d. 5.87n1 + 3.61n2 = 155

Option D is correct.

The isocost equation is 5.87 n₁ + 3.61 n₂ = 155

Step-by-step explanation:

The cost of item 1 is $5.87 per unit.

The cost of item 2 is $3.61 per unit.

Number of units of item 1 to be purchased is n₁

Number of units of item 2 to be purchased is n₂

Predetermined total purchase price = C = $155

Total cost of purchasing n₁ quantities of item 1 = $5.87n₁

Total cost of purchasing n₂ quantities of item 2 = $3.61n₂

The value of n₁ and n₂ have to be picked in such a way that the total amount spent on the two items (total amount spent on item 1, $5.87n₁ and total amount spent on item 2, $3.61n₂) just equals 155, that is,

5.87 n₁ + 3.61 n₂ = 155

This is option D.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
