Answer:
21.6
Explanation:
To solve for expressions with variables, substitute the variable's value is where the variable is in the expression.
The variable is y, and y's value is 0.3
Substitute y for 0.3
8(y+2.4)
= 8(0.3+2.4)
Now solve by following BEDMAS (brackets, exponents, division, multiplication, addition, subtraction).
= 8(0.3+2.4) <=Solve the brackets by adding
= 8(2.7) <= multiply
= 21.6
