Valentina purchased 3 shirts for $15.99 each, 2 pairs of pants for $25.00 each, and a pair of shoes for $39.99. The sales tax is 5%. How much did she pay?(1 point)
The total cost of the shirts is 3 * $15.99 = $<<3*15.99=47.97>>47.97.
The total cost of the pants is 2 * $25.00 = $<<2*25=50.00>>50.00.
The sum of the cost of the clothes is $47.97 + $50.00 + $39.99 = $<<47.97+50+39.99=137.96>>137.96.
The sales tax is $137.96 * 5/100 = $<<137.96*5/100=6.898>>6.898.
She paid $137.96 + $6.898 = $<<137.96+6.898=144.858>>144.858. Answer: \boxed{144.86}.
