At the beginning of the school year, Jamie had $500 in her savings account. She wants to have at least $200 left in the account

mario62 [17]

Answer:

Jamie should have reversed the inequality when using the division property of inequality.

Step-by-step explanation:

Jamie wrote

500 − 30x ≥ 200

Subtract 500 from both sides

500-500-30x ≥ 200-500

-30x ≥ -300

Divide both sides by -30

x ≥ 10

Instead of reversing the inequality when using the division property of inequality

500 − 30x ≥ 200

Subtract 500 from both sides

500-500-30x ≥ 200-500

-30x ≥ -300

Divide both sides by -30

x <or= 10

Steve can wash, fold, and iron a basket of laundry in two hours and prepare a meal in one hour. His roommate Mike can wash, fo

masha68 [24]

Answer: The absolute advantage in laundry is held by Steve while the comparative advantage in meal preparation is held by Mike.

Step-by-step explanation:

Absolute advantage is when an individual, firm or country can produce a good or service at a lower cost when compared to the other economic agent. When someone has absolute advantage, it means that the person uses fewer resources and spends less time in producing the good. Based on the explanation, Steve has absolute advantage in laundry since he spends two hours compared to Mike who uses 3hours.

Comparative advantage is when an individual, firm or government can produce a good or service with a lower opportunity cost when compared to the other person. Mike has a comparative advantage in the preparation of meal. It'll be better for Steve to focus his attention on laundry while Mike does the meal.

A daylily farm sells a portion of their daylilies and allows a portion to grow and divide. The recursive formula an=1.5(an-1)-10

zaharov [31]

Answer:

Hence, the number of daylilies in the first year were:

600

Step-by-step explanation:

It is given that:

the recursive formula $a_n=1.5(a_{n-1})-100$ represents the number of daylilies, a, after n years.

Also we are given that in the fifth year they have 2,225 daylilies.

i.e.

$a_5=2225$

Also,

$a_5=1.5a_4-100$

$a_4=1.5a_3-100$

This means that:

$a_5=1.5(1.5a_3-100)-100\\\\a_5=(1.5)^2a_3-100\times (1.5)-100$

Similarly,

$a_3=1.5a_2-100$

so,

$a_5=(1.5)^2\times (1.5a_2-100)-100\times (1.5)-100\\\\a_5=(1.5)^3a_2-(1.5)^2\times 100-(1.5)\times 100-100$

and so, putting $a_2$ in terms of $a_1$ we get:

$a_5=(1.5)^4a_1-(1.5)^3\times 100-(1.5)^2\times 100-(1.5)\times 100-100$

Now on putting the value of $a_5$ we find the value of $a_1$

$2225-(1.5)^4a_1-337.5-225-150-100\\\\2225=5.0625a_1-812.5\\\\2225+812.5=5.0625a_1\\\\3037.5=5.0625a_1\\\\a_1=\dfrac{3037.5}{5.0625}\\\\a_1=600$

Hence, the number of daylilies in the first year were:

600
