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?

The cost of  1 hammer and 2 wrenches is $34

The two equations represent the information provided in the question:

2h + w = 47 equation 1

h + 3w = 41 equation 2

h represents the price of a hammer.

w  represents the price of  a wrench.

The above equations are simultaneous equations and would be solved using the elimination method.

To determine the price of a wrench, take the following steps:

Multiply equation 2 by 2

2h + 6w = 82 equation 3

Subtract equation 1 from 3

5w = 35

Divide both sides of the equation by 5

w = 7

To determine the price of a hammer, take the following steps:

Substitute for w in equation 1

2h + 7 = 47

2h = 47 - 7

2h = 40

h = 40/2

h = 20

The price of a hammer = $20

Price of two wrenches = $7 x 2 = 14

Total cost is 20 + 14 = $34

$34

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

Penny=1 h + 3 w=$41

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

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
