Answer:

The cost of 1 calculator is $28.00

Step-by-step explanation:

You haven't mentioned the question. Anyways if you want to find the value of 1 calculator, the simplest method ( in my opinion) you could do so in the ratio method:

5 calculators : $140

1 calculators : x

( x is the cost of 1 calculator. You have to find x. )

Cross multiply both the ratios. Multiply 5 with x and 140 with 1.

5x = 140 × 1

5x = 140

Bring 5 to the other makes 140 divided upon 5, as it was multiplied with x.

x = $\frac{140}{5}$

x = $28

You could not only find the cost of 1 calculator, but any number of calculators. Just replace the number of calculators with 1 calculator that I have found the cost of.
