What are four equivalent expressions for 42+18

42+18=60

so
30+30
20+40
10+50
5+55

this should work:)

40 + 2 + 10 + 8
42 + 10 + 8
40 + 2 + 18
40 + 2 + 9 x 2

The answer would be 27 because assuming that each package has 1 bar of soap and 1 tube of toothpaste, after 27 packages they would run out of toothpaste
