Answer: 7x + 9y >_ (more or equal) 314
X + Y <_ ( less or equal) 35
Step-by-step explanation:
Find square footage of his yard
assuming is is roughtly a rectangle
area of rectangle=length times width
length=20ft
width=12 ft
area=length times width=20 times 12= 240 square feet
how many packages?
1 pack times x is at least 240
1 pack times x>240
50 times x>240
divide both sides by 50
x>4.8
you can't buy 0.8 pack, so round up
5 packs needed
they have gathered 26 kilograms so far
Because they already had 2 kilograms before the new recycling plan ,and the new plan was to gather 1 kilogram each week and its been 24 weeks
So u just have to add the 24 kilograms +2 kilograms=26 kilograms
