Question

Jenny bought 2 hammers and a wrench for $47. Penny bought 1 hammer and 3 wrenches for $41. How much is 1 hammer and 2 wrenches?

Answer 1

Answer: $34

Known:

Jenny=2 h (hammers) + 1 w (wrench)=$47

Penny=1 h + 3 w=$41

Solve:

2h+1w=47

1h+3w=41

2h+1w=47

2h+6w=82

5w=35

w=7

h=20

1h+2w=1(20)+2(7)=$34
