Explanation:
Using the formula, T = 176 - 0.8a, substitute the values of a or T from the table to solve for the unknown values:
a.
T = 132:
T = 176 - 0.8a
132 = 176 - 0.8a
132 - 176 = 176 - 0.8a - 176
132 - 176 = - 0.8a
-44 = -0.8a
-44/-0.8 = -0.8a/-0.8
55 = a
a = 70:
T = 176 - 0.8a
T = 176 - 0.8(70)
T = 176 - 56
T = 120
