Sagot :
Answer:
- Food bags - 175, pet blankets - 70, dog toys - 35
Step-by-step explanation:
Given:
- Dog food bags - f, cost of each $8,
- Pet blanket - b, cost of each $5
- Dog toy - t, cost of each $4
- Total cost $1890
Equations:
- 8f + 5b + 4t = 1890
- f = 5t
- b = 2t
Substitute values of b and t into first equation and solve for t:
- 8(5t) +5(2t) + 4t = 1890
- 40t + 10t + 4t = 1890
- 54t = 1890
- t = 1890/54
- t = 35
Find the values of f and b:
- f = 5*35 = 175
- b = 2*35 = 70
