Question

a math teacher decided to give a second quiz over the same material as the first quiz. to encourage students to show improvement, he announced that he would calculate the combined quiz score by starting with the first quiz score and adding \\(\frac{3}{4}\\) of the increase in score from their first quiz to their second quiz. maria scored 48 points on her first quiz and 68 points on her second quiz. what is her combined quiz score?\
a 60\
b 63\
c 77\
d 99

Explanation:

Step1: Calculate score increase

Increase = Second score - First score = $68 - 48 = 20$

Step2: Find 3/4 of the increase

$\frac{3}{4} \times 20 = 15$

Step3: Compute combined score

Combined score = First score + 15 = $48 + 15 = 63$

Answer:

B. 63
