wlad13 [49]

Answer: 76.28 approximately 76

Step-by-step explanation:

Ryan bought fishing gear for 51.50, 14.99 and 5.79.

Total fishing gear bought will be the addition of the 3 fishing gear.

51.50 + 14.99 + 5.79= 72.28

The sales tax is the multiplication of the total fishing gear by 0.05

= 72.28 × 0.05

= 3.614 which is approximately 4

Amount paid by Ryan will be

Total fishing gear + Sales tax

= 72.28 + 4

= 76.28 approximately 76.
