Question

Janice has saved $21.40. This is 1/3 of what she needs to save to buy a new piece of software. Write and solve an equation to find what is the total amount that Janice needs to save

Answer 1

$64.2

Explanation:

If she has 1/3 of the amount she needs to buy the piece of software, then we can assume that the amount she has, 21.4, can be multiplied by 3 to get the total amount of money required.

We can write it into the equation like this:

21.40(3)=c. (C stands for total cost)

Now, just solve.

21.40*3=64.2

64.2=c

She needs to save $64.2 to buy the piece of software.

Hope this helps!
