Answer 1

For a. set up a proportion.
80 oz ? oz
-------- = --------
1250 ft^2 ? ft^2

Answer 2

Do you have any idea which numbers fill in the ?'s?

Answer 3

I am totally lost
understand that the ? would be x I am not sure what you mean by 1250ft^2means

Answer 4

foot squared. It's just another way of writing out "square foot". A square foot is a foot times a foot.

Answer 5

okay

Answer 6

80 oz ? oz
------------ = --------
1250 sq feet ? square feet

Answer 7

Answer 8

no it's a proportion. You can cross multiply kinda. Just fill in the numbers first...

"How many ounces would be required to cover a 4,000-square-foot lawn?"

Answer 9

would it be 50oz then

Answer 10

hold up lemme do the math

Answer 11

okay i understand what you mean cross multiply

Answer 12

Cross multiplying isn't really a "thing" but I'm not going to whine about the math behind it. Essentially yeah.

Answer 13

lol gotcha

Answer 14

k, b. If Lazy Lawn costs $1.19 for a 32-ounce bag, what is the total cost to fertilize the lawn?

To start, how many 32 ounce bags will fill up a lawn that takes 80 ounces?

Answer 15

so the answer to 2nd part would be 304.64

Answer 16

don't think so. The way I see it is, we need EIGHTY ounces. The bags only come in 32, right?

1 bag: 32 (not enough)
2 bags: 64 (not enough)
3 bags: 96 (more than enough)

Answer 17

Actually I can't tell which lawn we're fertilizing

Answer 18

if it's the 4000 foot lawn. we need

1 bag: 32 (not enough)
2 bags: 64 (not enough)
3 bags: 96 (not enough)
4 bags: 128 (not enough)
8 bags: 256 ounces (enough)

Answer 19

Go with 8.

Answer 20

Answer 21

Answer 22

then i come up with 8 bag @ 1.19 which would be 9.52 in cost

Answer 23
