Answer:
4 goals
Step-by-step explanation:
Subtract 14 goals from 40 to get 26 goals that she needs to get.
She has to get it over 8 games so 26 goals / 8 games = 3.25 goals per game
We have to round up or she will not get enough goals so four goals per game.
Work backwards..
30 helmet + 30 left = 60$
60 + 15 charity = 75$
75 + 25 music = 100$

She worked 9 hours at baby-sitting and 6 hours at her parents store.
Step-by-step explanation:
Let,
Baby-sitting hours = x
Hours at parents store = y
Total hours = 15
Amount earned = $93
According to given statement;
x+y=15 Eqn 1
5x+8y=93 Eqn 2
Multiplying Eqn 1 by 5;

Subtracting Eqn 3 from Eqn 2;

Dividing both sides by 3;

Putting y=6 in Eqn 1

She worked 9 hours at baby-sitting and 6 hours at her parents store.
