John and Ariana bought school supplies, John spent $10.65 on 4 notebooks and 5 pens. Ariana spent $7.50 on 3 notebooks and 3 pen
timurjin [86]

Cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65

<h3><u>Solution:</u></h3>

Let "a" be the cost of 1 notebook

Let "b" be the cost of 1 pen

Given that John spent $10.65 on 4 notebooks and 5 pens

cost of 1 notebook x 4 + cost of 1 pen x 5 = 10.65

4a + 5b = 10.65 ------ eqn 1

Given that Ariana spent $7.50 on 3 notebooks and 3 pens

3a + 3b = 7.50 ----- eqn 2

Let us solve eqn 1 and eqn 2 to get the values of "a" and "b"

Multiply eqn 1 with 3

12a + 15b = 31.95  ---- eqn 3

Multiply eqn 2 with 4

12a + 12b = 30 ------ eqn 4

Subtract eqn 4 from eqn 3

12a + 15b = 31.95

12a + 12b = 30

(-) ---------------------

3b = 1.95

b = 0.65

Substitute b = 0.65 in eqn 1

4a + 5(0.65) = 10.65

4a = 7.4

a = 1.85

Thus cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65

Castel left the science museum and traveled toward the mountains. Sumalee left one hour later traveling 10 km/h faster in an eff
nadezda [96]

Castel's average speed from the science museum to mountains is 20 km/h

<h3>Average speed</h3>

Let x represent Castel' average speed.

Sumalee left one hour later and caught up with Castel after two hours, Let us assume the distance covered is d:

For Castel:

  • x = d / 3
  • d = 3x  

For Sumalee:

  • x + 10 = d / 2
  • d = 2x + 20

3x = 2x + 20

x = 20 km/h

Therefore Castel's average speed from the science museum to mountains is 20 km/h
