Time taken to oxidised metal A = 
Time taken to oxidised metal B =
seconds
So, ratio of metal A to metal B would be

Answer:
1334
Step-by-step explanation:
$250-$100 = $150
$200,000/ $150
1333.333
Round up
1334
Tax
$350x0.07
=$24.50
(0.07 is the 7% tax in decimal form)
Total cost
$350+$24.50
=$374.50
OR
$350x107%
=$374.50
1.07 is the table cost (100%) plus the sales tax (7%)
The table costs $374.50 with tax.
