zlopas [31]

Option D

Money earned by Marty is $ 16.72

<em><u>Solution:</u></em>

Given that, Marty started a lawn mowing business

He kept track of his expenses and earnings in a table

Lawn Mower = - $49.99

Gasoline = - $8.79

Moyer's yard = $ 40

Griffen's yard = $ 35.50

To find: Money earned by Marty

Total money earned = lawn mower + gasoline + moyers yard + griffens yard

Total money earned = -49.99 - 8.79 + 40 + 35.50

Total money earned = -58.78 + 40 + 35.50

Total money earned = -18.78 + 35.50 = 16.72

Thus money earned by Marty is $ 16.72

You can mow one acre in 126 minutes. i can mow one acre in 117 minutes. how long will it take you to mow a 0.17-acre lawn? 13 in
Morgarella [4.7K]

a) (0.17 ac)×(126 min/ac) = 21.42 min

b) I can mow 1/126 ac/min; you can mow 1/117 ac/min. Together, we can mow at a rate that is the sum of these:

... (1/126 + 1/117) ac/min = (117 + 126)/(126×117) = 243/14,742 ac/min

Then it will take 14,742/243 min/ac × 0.17 ac/lawn ≈ 10.31 min/lawn

Mandy and Priscilla shared a packet of stickers.At first, the number of stickers Mandy had was 1/4 of the number of stickers Pri
nignag [31]

Answer:

10 stickers.

Step-by-step explanation:

Let's say that Mandy has m stickers, and Priscilla has p stickers.

m = 1/4p

6/5(m + 28) = p + 28

6/5(1/4p + 28) = p + 28

1/4p + 28 = 5/6p + 23 and 1/3

5/6p - 1/4p = 28 - 23 and 1/3

10/12p - 3/12p = 84/3 - 70/3

7/12p = 14/3

p = (14/3)(12/7)

p = 8

At the beginning, Priscilla had 8 stickers. That means that Mandy had 1/4 * 8 = 8 / 4 = 2 stickers.

So, in the packet, there were 8 + 2 = 10 stickers.

Hope this helps!
