So the ratio 1:1 means that there are 32 cards of each colour (1 + 1 = 2, 64 ÷ 2 = 32). If we remove 8 red cards, there are then 24 red cards, and still 32 black cards. This ratio would be 24:32, which you can simplify to 12:16, then 6:8, and then 3:4, which is the final answer. I hope this helps!

Georgia [21]

Answer:

Done

Step-by-step explanation:

Teacher bought $21 worth of stickers and cardstock for his class.

Cost of stickers = $1.50 per sheet

Cost of 's' sheets = $1.5s

Cost of cardstock = $3.50 per pack

Cost of 'c' packs = $3.5c

Equation representing the relationship between sheet of stickers and packs of cardstocks will be,

1.5s + 3.5c = 21

3.5c = -1.5s + 21

1).  

  y-intercept of the line → (0, 6)

  x-intercept of the line → (14, 0)

  Therefore, equation of the line represents the line on the graph.

2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.

  Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.
