The temperature after 22 minutes is 75.75 degrees
<h3>Equations and exspressions</h3>
Given the resulting exponential model for the temperature, t, after m minutes can be approximated by the model t = 133(0.85)^m + 72.
If the time used is 22 minutes, the required temperature dring this time is expressed as:
t = 133(0.85)^22 + 72
t = 3.725 + 72
t = 75.75
Hence the temperature after 22 minutes is 75.75 degrees

Flip the situation:
X + 3.25 = 4.72
Subtract 3.25 from both sides
X + 3.25 - 3.25 = 4.72 - 3.25
X = 1.47
Answer:
125
Step-by-step explanation:
total earning = 500
saving = 200
reaminings = 500-200
temainings= 300
vehical expenses=100
now remainings= 300-100
remaining=200
closing= 75
remaings=200-75
remainings for entertainment= 125
