The cost of 45 packets of instant noodles given the direct variation is $52.335

<h3>Direct variation</h3>

let

Amount spent on noodles = n
Number of Packets purchased = p

n = k × p

Where,

k = constant of proportionality

34.88 = k × 30

34.88 = 30k

k = 34.88/30

k = 1.16266666666666

Approximately,

k = 1.163

Find n when p = 45

n = k × p

= 1.163 × 45

n = $52.335

six friends are going to buy a pizza. Their chices are to biu 2 medium 10-inch diameter pizzas for 7:00 each, or 1 large 14 inch

11111nata11111 [884]

For this question, we want to find out the greatest amount of area of pizza for the least amount of money:

So we have two pizzas with a 10 in. diameter. Let us take one of those pizzas.

The formula for area of a circle is $\pi r ^2$ ; So the area for one of these 10 in. pizzas would be $\pi (5)^2$ or 25 $\pi$ .

We have two of these pizzas, so the total area that we would get with $14 would be 25 $\pi$ *2 or 50 $\pi$ .

For the second case, we have one pizza with a 14 in. diameter.

The area of this pizza will be $\pi (7)^2$ or 49 $\pi$ .

So for $15 we can buy 49 $\pi$ worth of pizza.

The best deal would be to buy the two medium pizzas of 10 inch diameter, because for $14, you get 50 $\pi$ .
