1. Written Response: Danny bought 2 movie tickets and 10 pieces of
candy for $20. Chris bought 3 movie tickets and 30
pieces of candy for $45. Let x= the cost of one
movie ticket and let y = the cost of one piece of
candy.
2x + 10y = 20
3x + 30y = 45
Interpret the solution (5,1).

A movie ticket costs $5 and a piece of candy costs $1.

Step-by-step explanation:

2x + 10y = 20   or 2(5) + 10(1) = 20

3x + 30y = 45  or 3(15) + 30(1) = 45

9514 1404 393

Step-by-step explanation:

The problem statement tells you how to interpret the point (x, y) = (5, 1).

  "x= the cost of one movie ticket"

  x = 5 means the cost of one movie ticket is $5.00

__

  "y = the cost of one piece of candy"

  y = 1 means the cost of one piece of candy is $1.00

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
