Kayla wants to buy a camera for her parents. The camera is $150 and is 30% off for the holidays. If Kayla has $100, does she have enough to pay for the camera? Explain.

No.

Step-by-step explanation:

30% off would mean a discount of 0.30($150), or $45.  Subtracting this $45 discount from $150 yields $105.  Unfortunately, that's $5 more than her $100.

No.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
