Answer:
13 + 4(2) - 5(13) + 3
<em>multiply the numbers</em>
13 + 8 - 65 + 3
<em>calculate the sum or difference </em>
= -41
Step-by-step explanation:
Question A
take $100.80 divide it by 35 which would equal 2.88
so round that up for 3.0 for the closest answer
Question B
take 49.2 and divide it by 6 which would equal 8.2
so round it to the nearest number which would be 8.0
Question C
take 0.78 and divide it by 20L which would equal 0.039
so round that up to the closest number which would be 0.04L
32.5 % of lab are wireless devices
<em><u>Solution:</u></em>
Given that there was a total of 30 computers and the computer lab is removing 3 broken computers and adding 13 wireless devices
Now we can first find out total number of computers and devices in lab
total number of computers and devices in lab = 30 computers - 3 + 13 wireless devices
total number of computers and devices in lab = 30 - 3 + 13 = 40
So there are 40 computers and wireless devices in lab
<em><u>To find: what percent of the lab are wireless devices</u></em>
So we have to find what percent of 40 is 13
Let "a" be the required percent
a % of 40 = 13

32.5 % of of lab are wireless devices
