Including the tax what will be the mean cost of each shirt

C 44.59$.

1st shirt: 49.96$
2nd shirt: 49.96$
3rd shirt: 49.96$x50%=24.98$.

Total cost: (49.96$x2)+24.98=124.90$

Now it says that there a 7.1% tax of the total cost so:

Total cost x 7.1%: 124.90$x7.1%=8.87$

Now you have to add the tax to your total cost:

Total cost after tax: 8.87$+124.90$=133.77$

Finally, they ask what’s the cost of each shirt so you would have to divide the total cost after tax by 3 shirts:

Cost of each shirt: 133.77$/3=44.59$ for each shirt.

The equation is  125+22m=b
