Answer:

  • See below

Step-by-step explanation:

(a)

<u>Beast Boy spent:</u>

  • 5x

<u>Cyborg spent:</u>

  • 8(x - 1.5)

<u>They spent same amount:</u>

  • 5x = 8(x - 1.5)

(b)

  • 5x = 8x - 12
  • 8x - 5x = 12
  • 3x = 12
  • x = 4

(c)

  • 5*4 = 8(4 - 1.5)
  • 20 = 8*2.5
  • 20 = 20

  • Beast Boy bought 5 items that each cost $4
  • Cyborg bought 8 items that each cost $2.5

A paint shop stocks 1800 liters of paint 24% of the paint is white. The shops sells 18% of the white paint and 7% of the rest of
Anuta_ua [19.1K]

Answer:The amount of paint that was sold altogether is 173.36 litres

Step-by-step explanation:

The total amount of paint that the paint shop stocks is 1800 litres.

24% of the paint is white. It means that the amount of white paint would be

24/100 × 1800 = 0.24 × 1800 = 432 litres.

The amount of the remaining paint other than white would be

1800 - 432 = 1368 litres

The shops sells 18% of the white paint. This means that the amount of white paint sold by the shop will be

18/100 × 432 = 0.18 × 432 = 77.6 litres.

The shops sells 7% of the rest of the paint.

This means that the amount of the rest paint sold by the shop will be

7/100 × 1368 = 0.07 × 1368 = 95.76 litres.

The amount of paint that was sold altogether would be

77.6 + 95.76 = 173.36 litres
