Manuel is putting money into savings account. He starts with $550 in the savings account, and each week he adds $70. Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Manuel has been adding money. Write an equation relating S to W. Then use this equation to find the total amount of money in the savings account after 13 weeks. Equation:? Total amount of money after 13 weeks: $?

1,460

Step-by-step explanation:

550+W(13) = S

550+70*13 = S

550 + 910 = 1,460

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
