Question

Ibram got a job selling bags of peanuts at the local fairground. He is paid a fixed amount of $340 per week plus $0.84 per item sold. This is represented by the equation P = 0.84 + 340 where P is the amount he is paid for the week and n is the number of bags of peanuts he sold. How much will Ibram be paid if he sells 380 bags of peanuts? If Ibram sells 380 bags of peanuts, he will earn S How many bags of peanuts did Ibram sell if he earned $1,087.60? for the week. If Ibram has earned $1,087.60, he sold bags of peanuts.

Answer 1

Assuming the bags sold were for 1 week period.

1. $659.20 for 1 week and 380 bags of peanuts

2. 890 bags

Explanation:

The equation is missing the variable, n (the number of bags sold). I'll take the liberty to add it after the $0.84/bag term, where it belongs:

P = 0.84n + 340

The 340 is $340/week. n must be in units of "bags/week."

1. How much will Ibram be paid if he sells 380 bags of peanuts?

P = $0.84n + $340

n = 380 bags (we will assume in 1 week).

P = $0.84n + $340

P = $0.84(380) + $340

P = $659.20

2. How many bags of peanuts did Ibram sell if he earned $1,087.60?

P = $0.84n + $340

P = $1087.60

$1087.60 = $0.84n + $340

$1087.60 - $340 = $0.84n

$0.84n = $1087.60 - $340

$0.84n = $747.60

n = 890 bags ( ! - I'm impressed)
