Modeling System of Equations Per 2

Mathematics
1 answer:
DerKrebs [107]1 year ago
8 0

Based on the given information, you can write the following equations for the costs:

y1 = 35x + 75

y2 = 38x

If the cost is the same for both companies, you have:

35x + 75 = 38x

you can solve the previous equation for x to determine the number of people:

35x + 75 = 38x subtract 35x both sides

75 = 38x - 35x

75 = 3x divide by 3 both sides

75/3 = x

25 = x

Hence, the number of people is 25

An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $6750 and her st
pantera1 [17]

Answer:

3.5%

Step-by-step explanation:

1. calculate starting total

6750 + 4210=10960

starting amount = $10,960

2. calculate stock    A2's value

  • decreased by 18%

to make the percentage usable in this equation we need to divide it by 100 to get it in decimal form. ⇒ \frac{18}{100} = 0.18

  • multiply stock A1 by perctage decimal to get the amount decreased

6750(0.18)=1215 ($1,215)

  • subtract stock A1 by decreased amount to get stock A2's value

6750-1215=5535

A2 = $5,535

3. calculate stock    B2's value

  • increased by 20%

to make the percentage usable in this equation we need to divide it by 100 to get it in decimal form. ⇒ \frac{20}{100} = 0.20

  • multiply stock B1 by perctage decimal to get the amount increased

4210(0.20)=842 ($842)

  • add stock B1 with increased amount to get stock B2's value

4210+842=5052

B2 = $5,052

4. get new amount of account

5052+5535=10587

new amount = $10,587

5. find percentage decrease of starting amount to new amount

  • divide starting amount by the new amount

\frac{10960}{10587} = 1.03523188816

  • then subtract by 1

1.03523188816-1 =0.03523188816

  • multiply by 100 to convert to percentage form

0.03523188816(100) =3.523188816

  • and round to <u>nearest tenth</u>

answer is ≈ 3.5%
