Answer 1

let S1 and S2 be the scores

Answer 2

Answer:

48 throws

Step-by-step explanation:

for every 5 throws 2 are correct.

for 70 throws = 2 × 70 / 5

= 28 corrects

remaining throws = 100 - 70 = 30

80% of 30 = 30 × 80 / 100

= 24 corrects

total corrects = 28 + 24 = 52 corrects.

number of throws she missed = 100 - 52 = 48 throws.

hence the answer.
