The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs

<h3>Equation</h3>

  • Total attendance = 75 people
  • Cookies in each pack = 12
  • Brownies in each pack = 15
  • Number of cookies pack = c
  • Number of brownies pack = b

15b + 12c = 75

If 1 package of brownies is bought

15b + 12c = 75

15(1) + 12c = 75

15 + 12c = 75

12c = 75 - 15

12c = 60

c = 60/12

c = 5 packs

  • It is a reasonable value in this context

If 9 packages of brownies are bought

15b + 12c = 75

15(9) + 12c = 75

135 + 12c = 75

12c = 75 - 135

12c = -60

c = -60/12

c = -5 packs

  • The value is not reasonable in this context

motikmotik

Answer:

Derek; by 11600 m.

Step-by-step explanation:

Convert 1.5km into m.

1.5 is 1500m.

1500 * 12 = 18000 m

8 * 800 <= Lucy

6400 m  <= Lucy's distance

18000-6400=11600m

John sells plain cakes for $8 and decorated cakes for $12. On a particular day, John started with a total of 100 cakes, and sold
qaws [65]

x+ y =  96   →     y = 96 - x     (1)

And the price per plain cake * the number he sold + price of the decorated cake * the number he sold = total sales

So

8x + 12y = 800    (2)

Subbing (1) into (2), we have that

8x + 12 (96 - x)  = 800   simplify

8x + 1152 - 12x  = 800       

-4x + 1152 = 800    subtract 1152 from both sides

-4x  = -352     divide both sides by -4

x = 88   = the number of plain cakes he sold

And 96 - x =  96 - 88  = 8   = the number of decorated cakes he sold
