Danielle earned $969 last week if she sold $4,400 in electronics merchandise
<h3><u><em>Solution:</em></u></h3>
Given that, Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.
She also earns a base salary of $650 per week.
We have to find how much did she earn last week if she sold $4,400 in electronics merchandise?
Now, we know that, earned amount = base salary + commission
Given that she earns a 7.25% commission on everything she sells
<em><u>So commission earned for selling $ 4400 is given as:</u></em>
commission earned = 7.25 % of 4400
Earned amount = base salary + commission = 650 + 319 = 969
Hence, she earned $969 last week
7 + 14

5(14 + 19)
60 - 36

300000 all you had to do was round the number down after the 1 significant figure
you round down with
1,2,3,4
and round up with
5,6,7,8,9
so if it asked for 78453
to 2 significant figures you count the numbers and round after that
so 78|453 and since 4 is the next number and it is less that 5 we round down which means it becomes 78000 with is lower than 78453
but if we had 0.0247
and it asked for this number to 2 significant figures all you need to do is count the SIGNIFICANT figures significant means anything with value so that is 1,2,3,4,5,6,7,8,9,10.... 0 has no value therefore we ignore 0 and start counting at the first figure larger than 0
if we go back to 0.0247 that would be the 2 so 2 significant figure of 0.0247 would equal
0.024|7
7 is larger than 5 so we round up to
0.025
tadaa i hope that helped
