Answer 1

A. $22 (5x2 + 4x3)

B. The exact cost is 5.50 x 2 + 4.25 x3
= $23.75

C. $25-$23.75 = $1.25

Answer 2

Answer:

Step-by-step explanation:

Part A:

Total cost for 2 adults at $5.5 each and 3 students at $4.25 each

= 2*5.5 + 3*4.25

~= 12 +  12

= $24

Part B:

Exact cost = 11 + 12.75

= $23.75

Part C: If the family pays $25,

the exact change = 25 - 23.75

= $1.25
