Answer:
66 °F
Step-by-step explanation:
At 4 P.M., the temperature had decreased by 3° from the temperature at 3 P.M., so was ...
4 P.M. temp = 78 °F -3° = 75 °F
This was repeated until 7 P.M.
5 P.M. temp = 75 °F -3° = 72 °F
6 P.M. temp = 72 °F -3° = 69 °F
7 P.M. temp = 69 °F -3° = 66 °F
The temperature at 7 P.M. was 66 °F.
__
Of course the repeated subtraction can be simplified using multiplication. The subtraction of 3° four times is equivalent to the subtraction of . . .
(3°)(4) = 12°
That is, the temperature at 7 P.M. is ...
78 °F -3°×4 = 78 °F -12° = 66 °F
Answer:
Step-by-step explanation:
x_0=0
x_1 = $40
so delta change is $40. Now we can write the equation as
y = 40x, where y is the total saving account amount.
So after the 6th deposit, her total saving is $240.
y = 40(6) => 240
