At a shooting range each shot costs 20c. if you hit the target you recieve 30c. emma has 20 shots and makes a loss of 70c. how many hits did she get?

Each shot cost 20c.

She had 20 shots, so the total it cost her for shooting was 20 x 20c = $4.00

Since she only lost 70c, this means the amount she earned for hits was 4.00 - 0.70 = $3.30

Divide that amount by the amount she makes per hit:

3.30 / 0.30 = 11

She made 11 hits.

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35
