he have left 4.45 kg

The computation of he have left is as follows:

= Total salt purchase - salt used on his sidewalk - sales used on the driveway

= 10 - 1 \frac{3}{4} - 3 \frac{4}{5}\\\\= 10 - \frac{7}{4} - \frac{19}{5}\\\\= \frac{200 - 35 -76 }{20}  \\\\= \frac{89}{20}

= 4.45 kg

Hence, he have left 4.45 kg

Answer:

Median = 45

Since the given data set is already in ascending order, we we just have to find the middle most number of the data set:

There are 2 middle numbers 40 and 50, so to find the middle most number find their average:

(40 + 50) / 2 = 45

Median = 45

A bicycle has a listed price of $625.99 before tax. If the sales tax rate is 7.5%, find the total cost of the bicycle with sales
Serhud [2]
With tax, it would be 107.5% of 625.99. 107.5% is 1.075 in decimal form so you do 1.075(625.99). That gives the rounded answer of $672.94. :)
