Answer:
x = 55
Step-by-step explanation:
(x - 14) + 99 + 220 = 360
x - 14 + 99 + 220 = 360
x - 14 + 319 = 360
x + 305 = 360
x = 360 - 305
x = 55

Answer:
1.) Amount of potting soil purchased last week.
2) 2p + 4 = 28
3.) 12 lbs
Step-by-step explanation:
1.) The unknown information is what we intend to find out using the information given, which is the amount of potting soil Emmanuel bought last week.
2.)
Let amount of potting soil bought last week = p
Amount bought this week = 2p + 4
Since amount bought this week = 28

28 - 4 = 2p
24 = 2p
p = 24 / 2
p = 12
