Answer:
D. 4r + 3(10 – r) = 37
Explanation:
Let r be the roller coaster ride. Since it costs 4 tickets, this gives us the expression 4r.
We know that there were 10 rides total; this leaves Michael 10-r for the number of times he rode the boat ride.
Each boat ride costs 3 tickets; this gives us the expression
3(10-r)
Together, this gives us
4r+3(10-r) = 37
Answer:
$53 + $14.50 = x
x = $67.50
Step-by-step explanation:
Let us assume the original price be x
It is given that
The discounted ticket is $53
And, the discounted concert ticket cost is $14.50 lower than the orginial price
So, the equation is
$53 + $14.50 = x

= $67.50
Hence, x denotes the original price of the ticket
We simply added the above two amounts
