Answer:
3:50pm
Time Keisha went to the park- 1:30pm
Time spent for hiking- 1hour 35 minutes
Time spent at the picnic area- 45 minutes
1: 30pm
<u>+1. 35mi</u>n
<u> 2: 65pm</u>
But 60 minutes is 1 hour so the 65 will be changed to 1 hour 5 minutes making it
3: 05pm
3: 05pm
<u>+0: 45min</u>
<u> 3: 50pm</u>
Hence the time Keisha left the park was 3:50pm
1/4 bc if you take the fraction 3/12 and simply it’s 1/4
Using linear function concepts, it is found that:
- a) It costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.
- b) f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.

A <em>linear function </em>has the format given by:

In which:
- m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
The equation for the cost of h kilowatt hours (kWh) of electricity used in excess of 250 kWh is of:

Item a:
- The slope is of
, which means that it costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.
Item b:

250 + 90 = 340.
f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.
