Answer:
Step-by-step explanation:
Mp=$1200
Let sp be x
SP=MP-discount% of MP
x=1200-15/100 * 1200
x=120000-18000/100
x=102000/100
x=1020
the amount of money person saves=MP-SP
=$1200-$1020
=$180
therefore he saves $180

Answer:
4, 7, 12, 19 and 103
Step-by-step explanation:
Substitute n = 1, 2, 3, 4, 10 into the n th term formula, that is
1² + 3 = 1 + 3 = 4
2² + 3 = 4 + 3 = 7
3² + 3 = 9 + 3 = 12
4² + 3 = 16 + 3 = 19
Thus the first 4 terms are 4, 7, 12, 19
10² + 3 = 100 + 3 = 103
Thus the 10 th term is 103
Answer: No
Step-by-step explanation:
Given: The San Diego Safari Park charges $18 for parking, and an admission fee of $56.
This can be represented by the equation c = 56p + 18, where c is the total cost and p is the number of people.
Equation of direct proportion: 
But here we have a y-intercept as 18.
So, we cannot say there is a proportional relation ship between c and p.
