Ellie, her friends, and her mother went out to dinner. The drinks and food bill came to $94.95. Maria's mother will pay for herself and the friends, but Maria will pay for her own meal. Each meal cost the same and we will not worry about tax. Maria has a $20 bill. Will she have enough? If so, how much is left over? if not, how much does she need? Mother has a $100 bill. Will she have enough? if so, hownmuch is left over? if not how much does she need?​

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

hello,

as   long as they add up to 180 its correct.
