So the way you would do this problem would be to solve for how many pens he was able to buy if he bought $9.75 worth of pens for $0.75 each. so to find the number of pens you would do 9.75/0.75, which equals a total of 13 pens. so he bought 4 times as many pencils so to find the number of pencils he purchased you would multiply 13 by 4 which equals 52 total pencils. to find the cost that aaron paid total you would multiply 52x0.35 which equals $18.20

jok3333 [9.3K]

Here, we have to find the number of guests who can attend their weeding without exceeding the set budget of $10,000

Since the catering fee of $150 is waived, we do not consider this figure in our analysis

There is a constant which is the venue costs of $2,000 and a variable cost of $80 per guest for the reception.

Let us assume "X" guests arrive for the reception, so we can form the equation as shown below:

80X + 2,000 = 10,000 (Since the total budget for the wedding is $10,000)

80X = 8000

8X = 800

X =100

Therefore, Selena and Ronald can invite 100 guests for the wedding without going over their budget
