Question

Dwight is taking a drawing class the drawing pencils coast $.97 a piece and a sketchbook costs $5.95 Dwight spent a total of $11.77 solve the equation $0.97n =$5.95=11.77 to find the number of n pencils he bought

Answer 1

Answer : $\bold{Number \: of \: pencils \: = \: 6}$


Explanation :-

Given :

Each pencil cost = $ 0.97

Sketch Book cost = $ 5.95

Total spent = $ 11.77


Finding the Total cost of pencils :-

Total money he spent - Cost of the sketch book

$11.77 - $5.95

=> 11.77 - 5.95

=> 5.82

So, Total cost of pencils = $5.82


Finding number of pencils :-

Each pencil = $0.97

Total cost of pencils = $5.82

=> Number of pencils = 5.82/0.97

=> Number of pencils = 6

So, Number of pencils (n) = 6


Solving given equation :-

$0.97n + $5.95=11.77

$0.97(6) + $5.95 = 11.77

0.97(6) + 5.95 = 11.77

5.82 + 5.95 = 11.77

11.77 = 11.77

________________________________

Alternative Method to find the value (n) :-

$0.97n + $5.95= $11.77

0.97n + 5.95 = 11.77

0.97n = 11.77 - 5.95

0.97n = 5.82

n = 5.82/0.97

n = 6.
