1.) a. 20 : 4? means? * 4 = 20 → replace? with 5.

b. 2,725 : 5? means? * 5 = 2,725 → replace? with 545

c.? : 5 = 0 → replace? with 0.

2) 1,475 / 25 = 59

They used 59 boxes for this year.

3) 18 per haircut; 70 per perm

4,608 = 18h + 70 (36)

4,608 - 2,520 = 18h

2,088 = 18h

2,088/18 = h

116 = h

Grace did 116 haircuts.

4) 575 + 13 (118) = 575 + 1,534 = 2,109 total expense.

5) 2,240 miles / 320 miles = 7 tanks of gas used.

7 tanks * 39 = 273 cost of the gas used.
