Answer:

6x + 4y ≤ 50

x + y ≥ 10

Step-by-step explanation:

$6 is the cost of stuffed animals $4 is the cost of toy trucks and the her maximum budget is $50 it would be 6x+4y is less then or equal to 50 and there is AT LEAST 10 people so the amounts which are x and y would be equal to or greater than 10.

Answer:

$6x+4y\leq 50$

$x+y\geq 10$

Step-by-step explanation:

$x$ represents the number of stuffed animals.

$y$ represents the number of toy trucks.

Now, according to the problem, she found stuffed animals for $6.00 each and toy trucks for $4.00 each. Also, Laura has a restricted budget of $50. All these can be expressde as

$6x+4y\leq 50$

Also, the problem states that Laura wants to provide one partu favor per person to at least 10 people, that means

$x+y\geq 10$ , because "at least" represents a minimum value, which is expressed with $\geq$ .

Therefore, the inequality system that models this situation is

$6x+4y\leq 50$

$x+y\geq 10$

Answer:

$f(t)=50+10(t-70)$

Step-by-step explanation:

Let the outside temperature be $t$ degree.

So, when $t=70$ degree, number of members, $f(t)=50$

Now, for every degree rise in temperature, 10 members gets added.

So, when the temperature is $t$ degrees, rise in temperature is $(t-70)$ degrees.

Therefore,

For $(t-70)$ degrees rise, number of members added = $10(t-70)$

Hence, total number of members added as a function of temperature is given as the sum of members at $t= 70$ degrees and for $(t-70)$ degrees rise. This gives,
