Answer:

  1. Number of bracelet Jessica can make in 30 minutes=2
  2. Number of bracelet Jessica can make in 60 minutes=4
  3. Number of bracelet Jessica can make in 90 minutes=6
  4. Number of bracelet Jessica can make in 120 minutes=8
  5. Number of bracelet Jessica can make in 180 minutes=12

Jessica can make <u>12 bracelet</u> in 180 minutes (3 hours).

Step-by-step explanation:

  • <u>Unitary method</u>

Number of bracelet Jessica can make in 30 minutes=2

Number of bracelet Jessica can make in 180 minutes=(180×2)/30=12

or,

  • <u>Arithmetic method</u>

Number of bracelet made by Jessica is directly proportional to the time taken by her.

Number of bracelet made by Jessica=k×time taken by her, where k is a constant

  • 2k=30
  • 4k=60
  • 6k=90
  • 8k=120

In all cases value of k is 15

Therefore,

Let the number of bracelet be x and putting the value of k, we get

xk=180 minutes (3 hours)

15x=180

x=180/15

x=12

Please answer this correctly which is the correct options
MakcuM [25]

The first two are equivalent to 15 = k + 13

8 = k + 13 - 7 → ( add 7 to both sides )

8 + 7 = k + 13 ⇒ 15 = k + 13 ' is equivalent '

12 = k + 13 - 3 → ( add 3 to both sides )

12 + 3 = k + 13 ' is equivalent '

A used car is priced at $2,695. If you borrow the money for the car, your payments will be $122 a month for 30 months. How much
Studentka2010 [4]

Answer: $965

Step-by-step explanation:

The used car is priced at $2,695.

If you borrow the money for the car, your payments will be $122 a month for 30 months. This means that the total amount of money that you would have paid at the end of 30 months at a rate of $122 per month is the amount paid per month multiplied by the total number of months. It becomes

Total payment = 122×30 = $3660

This means that you ended up paying higher than you would have paid if you paid cash.

Amount that you would have saved = amount paid over 30 months - cost of the car

Amount that you would have saved

= 3660 - 2695 = $965
