Answer:
2.25 + 1 1/3=3.5833333 combined number of pounds of mulch and gravel sold.
2.25/3.583333 X 172=108 pounds of mulch that the supplier sells
(1 1/3) / 3.583333 X 172=64 pounds of gravel that the supplier sells.
Step-by-step explanation:
Let 'x' = pounds of gravel The ratio of mulch to gravel is given 2 1/4 / 1 1/3 Which equals 9/4 / 4/3 = 27/16
So the total gravel and much is equal to x + 27/16x = 172
Solving for 'x'
43/16 x = 172
x = 172 (16/43) = 64 pounds of gravel Mulch = 27/16x = 64 (27/16)= 108 pounds
