Answer:
$30.76
Step-by-step explanation:
Subtract the costs of her purchases from her total of 50:
50 - (14.99 + 3(4) + 2.25)
50 - (14.99 + 12 + 2.25)
50 - 29.24
= 20.76
Now, add the $10 that she found to this:
20.76 + 10
= 30.76
So, when she left the store, Lucy had $30.76
a = 9
a+11=20
Subtract 11 from each side
a+11-11 = 20-11
Adult price is: $12
Children price is: $11
Exact Form-9+√69÷6
Decimal form-2.88443731
