Decimals that contain a zero in the tenth position can be thought of as a fraction over 100 as the tenth isn't occupied and the hundredth correlates to the 100 as a denominator.

It is EXACTLY equal to 13, whereas the second equation equals

I’m not gonna lie. I’m just answering so I could upload my question
First calculate the area of the pool, which is 15 x 15, = 225 sq meter,
and just multiply the cost for each sq meter by the area,
17.5 x 225
therefore the cost will be $3937.5
For question 1, We need to calculate the total, find the tax, then add the shipping cost to the total. (70+30+38=138) now we find the tax (138*0.06=8.28) Now we add the tax and cost together and then the shipping and handling and we have our answer (138+8.28+10.75=157.03) So your answer is A.
For question 2, We need to calculate the total and then find the tax. So, we do this: 25.67*3=77.01. Then we add the skirt to the total (77.01+23.55=100.56). Finally, we calculate the tax cost (100.56*0.08=8.0448). So our total is (100.56+8.0448=108.6048) So the answer is A.
