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)
$80.98
$144.86
$137.96
$85.03
To calculate the subtotal for the shirts:
3 shirts * $15.99/shirt = $<<3*15.99=47.97>>47.97
To calculate the subtotal for the pants:
2 pairs * $25.00/pair = $<<2*25=50.00>>50.00
To calculate the subtotal for all items:
$47.97 (shirts) + $50.00 (pants) + $39.99 (shoes) = $<<47.97+50+39.99=137.96>>137.96
To calculate the sales tax:
5% of $137.96 = $<<0.05*137.96=6.90>>6.90
Finally, to calculate the total paid:
$137.96 (subtotal) + $6.90 (sales tax) = $<<137.96+6.90=144.86>>144.86
So, Valentina paid $144.86. Answer: \boxed{144.86}.

For the first question:
The total cost of the shirts is 3 shirts * $15.99/shirt = $<<3*15.99=47.97>>47.97
The total cost of the pants is 2 pairs * $25.00/pair = $<<2*25=50.00>>50.00
The total cost of the shoes is $39.99
The subtotal is $47.97 + $50.00 + $39.99 = $137.96
The sales tax is 5% of $137.96 = $137.96 * 0.05 = $<<137.96*0.05=6.90>>6.90
So Valentina paid $137.96 + $6.90 = $144.86.
For the second question:
The tip is 20% of $13.99 = $13.99 * 0.20 = $<<13.99*0.20=2.798>>2.80
The total cost is $13.99 + $2.80 = $<<13.99+2.80=16.79>>16.79.
For the third question:
The baby's actual weight is 8.25 pounds
Simon's estimate was 6.5 pounds
The percent error is given by (| Actual Value - Estimated Value| / Actual Value) * 100%
= (| 8.25 - 6.5| / 8.25) * 100%
= (1.75 / 8.25) * 100%
= (0.2121) * 100%
= 21.21%
For the fourth question:
The percent error is given by ((| Actual Value - Estimated Value|) / Actual Value) * 100%
= ((| $21,800 - $25,500|) / $25,500) * 100%
= (($3,700) / $25,500) * 100%
= (0.1451) * 100%
= 14.51%
For the fifth question:
The whiteboard is 7.5 feet long.
To convert to inches, we multiply by 12 inches/foot:
7.5 feet * 12 inches/foot = 90 inches.
For the sixth question:
35 pounds * 0.45 kilograms/pound = 15.75 kilograms.
