Question

Macy is playing a dart game. She can throw
some darts. For each dart hitting the dartboard,
she will get +30 marks, for each dart missing,
she will get -15 marks. If she only misses 1 dart
in the game and her final mark is 75 marks, find
the number of times that she hits the dartboard.

Answer 1

Answer:

Macy hit the dartboard 3 times.

Step-by-step explanation:

for hitting 1 dart = +30 marks

for hitting 2 darts= + 30 marks

make a total of it 30+30= 60 marks

but her final marks are 75,

so, add another +30 marks

it becomes +90 marks.

but, she misses 1 dart so substract -15 marks from +90 marks.

90-15 = 75 marks

so, your answer is 3 darts.
