Let G=cost of gold ticket.
Silver ticket costs
S=G/2+7, and
S=6G/5-14
Equate both,
6G/5-14=G/2+7
simplify
6G/5-G/2 = 7+14
12G/10-5G/10=21
7G/10=21
Cross multiply
G=10*21/7=30 => Gold tickets cost $30 each.
S=G/2+7=30/2+7=15+7=22
Silver tickets cost $22 each.
The first 100 gold ticket purchasers will therefore save $30-$22=$8 each ticket.
Answer:
$570
Step-by-step explanation:
Given that:
For each hour of tutoring, Lena earns 30 dollars.
E is her earning and
H is the number of hours for which she tutors.
To find:
Equation relating E to H.
Solution:
Let Lena tutors for 1 hour, then the earning = 30 dollars
Let Lena tutors for 2 hours, then the earning = 30+30 OR 230 = 60 dollars
Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 330 = 90 dollars
If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.
So, the equation that relates E to H is given as:
Now, it is given that she tutors for 19 hours.
Let us put H = 19 hours in the above equation:
Therefore, the earning for 19 hours of tutoring is <em>570 Dollars.</em>
