Tyler went to the supermarket to buy food for a food pantry. He has $36, and can carry up to 20 pounds of food in his backpack.

sattari [20]

Answer:

Solutions: (2,10), (4,5)

Not solutions: (1,12), (6,10), (12,8), (18,6)

Step-by-step explanation:

Let x be the number of packages of pasta and y be the number of jars of pasta sauce. If pasta costs $1 for a 1-pound package, then x packages of pasta cost $x and weigh x pounds. If pasta sauce costs $3 for a 1.5 pound jar, then y jars cost $3y and weigh 1.5y pounds.

1. Tyler has $36, then

$x+3y\le 36.$

2. Tyler can carry up to 20 pounds of food in his backpack, then

$x+1.5y\le 20.$

You get the following system of inequalities:

$\left\{\begin{array}{l}x+3y\le 36\\ x+1.5y\le 20\end{array}\right.$

Now substitute the coordinates of each point:

<u>(1,12):</u>

$\left\{\begin{array}{l}1+3\cdot 12=37> 36\\ 1+1.5\cdot 12=19\le 20\end{array}\right.$

False, because first inequality doesn't hold.

<u>(2,10):</u>

$\left\{\begin{array}{l}2+3\cdot 10=32\le 36\\ 2+1.5\cdot 10=17\le 20\end{array}\right.$

True, both inequalities hold.

<u>(4,5):</u>

$\left\{\begin{array}{l}4+3\cdot 5=19\le 36\\ 4+1.5\cdot 5=11.5\le 20\end{array}\right.$

True, both inequalities hold.

<u>(6,10):</u>

$\left\{\begin{array}{l}6+3\cdot 10=36\le 36\\ 6+1.5\cdot 10=21> 20\end{array}\right.$

False, because secondt inequality doesn't hold.

<u>(12,8):</u>

$\left\{\begin{array}{l}12+3\cdot 8=36\le 36\\ 12+1.5\cdot 8=24> 20\end{array}\right.$

False, because second inequality doesn't hold.

<u>(18,6):</u>

$\left\{\begin{array}{l}18+3\cdot 6=36\le 36\\ 18+1.5\cdot 6=27> 20\end{array}\right.$

False, because second inequality doesn't hold.

A flower vendor sells roses for 50 cents each. how much does she pay per flower if she makes $6.00 on every $20 worth sold

kkurt [141]

We are given

selling price of one flower is $0.50

so, $SP=0.50$

Let's assume

she sold 'n' flowers to get $20

so, total amount she get after selling 'n' flowers is

$=0.50*n$

$=0.50n$

This is supposed to be $20

so, we can set it equal to 20

$20=0.50n$

now, we can solve for n

we get

$n=40$

we are given

she makes $6.00 on every $20 worth sold

so, we can find cost of 40 flowers is 20-6

total cost is 14

or cost of 40 flowers is $14

now, we can find cost of one flower

$CP=\frac{14}{40}$

$CP=0.35$

so, cost of each flower is 35 cents...............Answer
