Given:
- total number of masks= 200
- cost of 1 mask= Rs. 5
so, total cost fir 200 masks=
200×5
= 1000
therefore, Joe paid Rs. 1000 altogether.
He bought 200 masks.
And 1 mask costs Rs. 5. So for the equation you do...
1 mask = Rs. 5
200 masks = x(unknown)
➡️ x = Rs. 5 * 200 masks/ 1 mask
➡️ x = 1,000/1
➡️ x = Rs. 1,000
And 1 mask costs Rs. 5. So for the equation you do...
1 mask = Rs. 5
200 masks = x(unknown)
➡️ x = Rs. 5 * 200 masks/ 1 mask
➡️ x = 1,000/1
➡️ x = Rs. 1,000
