Answer 1

Answer:

(b) 25 muffins

(c) 38 muffins

Step-by-step explanation:

Given:

• A cookie cost $0.80
• A muffin costs $1.60
• buy 200 treats
• spend $200 or less

Forming system of linear equations:

muffins (m) + cookies (c) = 200 treats

1.60m + 0.80c = $200

Solve by Substitution:

m + c = 200

1.6m + 0.8c = 200

using m + c = 200, solve for m by subtracting c:

m + c - c = 200 - c

m = 200 - c

we can now plug in m tot he second equation,

1.6(200 - c) + 0.8c = 200

320 - 0.8c = 200

320 - 320 - 0.8c = 200 - 320

-0.8c = -120

-0.8c/-0.8 = -120/-0.8

c = 150

plug c back in to find m,

m = 200 - c

m = 200 - 150

m = 50

(b) if you buy 200 cookies, then how many muffins?

we use this equation as we want to stay in the price limit: 1.6m + 0.8c = 200

c = 200 so 1.6m + 0.8(200) = 200

1.6m + 0.8(200) = 200

1.6m + 160 = 200

1.6m = 200 - 160

1.6m = 40

1.6m/1.6 = 40/1.6

m = 25
