Min jee wants to build a small patio using either brick or paver stones. it will be 70 inches long and 49 inches wide. each brick covers an area of 3 1/2 inches by 7 1/2 inches, and cost $0.59. each paver covers an areas 8.4 inches by 8.4 inches and costs $1.88. what would be less expensive to use, and by how much?

1 Brick = 3.5 in by 7.5 in  = 26.25 sq. in. and costs $0.59
1 Paver = 8.4 in by 8.4 in  = 70.56 sq. in. and costs $1.88

patio's area 70 * 49 = 3430 sq. in.

number of Bricks to complete the Patio :

3430 / 26.25 = 130.67 round up to 131

total cost of bricks:
131 * $0.59 = $77.29

number of Pavers to complete the Patio:

3430  / 70.56 = 48.6 round up to 49

total cost of pavers:

49 * $1.88 = $92.12

 $92.12 - $77.29 = 14.83

  the bricks would cost less by $14.83
