A football team received 3 penalties for 15 yards each, 1 for5 yards, and1 for half the distance to the goal from the 34 - yard line. Write and find the value of an integer expression to find the total change in their field position from these penalties.

The first penalty they received is three 15 yards so total yards is 3 (15 yards)

the second penalty is one 5 yard

the last penalty is half the 34 yard line (34 yard) / 2

total change = 3 (15 yards) + 5 yrad + (34 yard) / 2

= 45 yards + 5 yards + 17 yards = 67yards
