Joshua sells a pack of pens for 3.15 which is 5 percent more than he pays for them. which equation will find x, the amount he pays for a pack of pens? how many solutions will this equation have? x+0.05x=3.15, which has infinitely many solutions x+0.5x=3.15, which has one solution x+0.05×=3.15 which has one solution 0.05×=3.15, which has no solution

X= the amount he pays for a pack of pen

x+0.05x=3.15   , which has one solution.

1.05x=3.15
x=3.15/1.05=3

he pays for a pack of pens 3

 x+0.05x=3.15   , which has one solution.

I believe that the answer is 10.05 to the nearest tenth of a decimal
