Angela's score in a test was 5 more than double John's score. If John's score was 45 marks, how many marks did Angela score?

Answer 1

Let John's score be denoted as \( J \). According to the information provided, John's score is:

\[ J = 45 \]

Angela's score, denoted as \( A \), is described as being 5 more than double John's score. Therefore, we can express Angela's score mathematically as follows:

\[ A = 2J + 5 \]

Now, substituting John's score into the equation:

\[ A = 2 \times 45 + 5 \]

Calculating this step-by-step:

1. First, calculate \( 2 \times 45 \): \[ 2 \times 45 = 90 \]

2. Next, add 5 to this result: \[ 90 + 5 = 95 \]

Thus, Angela's score is:

\[ A = 95 \]

Therefore, Angela scored 95 marks.
