1. Answer: each hospice costs \$4 and each shrub costs \$9

Step-by-step explanation:

Let x represent the cost of one hospice.

Let y represent the cost of one shrub.

Mike spent \$71 on four hospice and seven Travis. This means that

4x + 7y = 71- – – – – – – – – – – – -1

Danielle spent \$53 on 13 hospice and three shrubs. This means that

13x + 3y = 53- – – – – – – – – – – 2

Multiplying equation 1 by 13 and equation 2 by 4, it becomes

52x + 91y = 923

52x + 12y = 212

Subtracting, it becomes

79y = 711

y = 711/79

y = 9

Substituting y = 9 into equation 1, it becomes

4x + 7 × 9 = 71

4x + 63 = 71

4x = 71 – 63

4x = 8

x = 8/4 = 2

2. Answer: \$71
