a=0.03t+1.4 t=8

To find the value of 'a' when 't' is equal to 8 in the given equation, you can substitute the value of 't' into the equation and solve for 'a'.

Given equation: a = 0.03t + 1.4

Substituting t = 8 into the equation:
a = 0.03(8) + 1.4

Now, you can evaluate the expression:

a = 0.24 + 1.4

Add the numbers together:

a = 1.64

So, when t = 8, a = 1.64.
