Given:
salary of 1,200 a month plus 3% of the sales price.
a) <span>The total of the sales prices of all the vehicles Sid sold during the first month on the job was $72000. What was Sid's income?
</span>72,000 x 3% = 2,160 commission
1,200 + 2,160 = 3,360
b) <span>In order to make $6000 in a single month, how much selling must Sid do?
</span>6,000 - 1,200 = 4,800
4,800 / 3% = 160,000 per month.
c) <span>Write a linear equation that expresses Sid's monthly income y in terms of the value x of the vehicles Sid sold
y = 1,200 + 3%x ; where x is the sales price of every vehicle sold.</span>
Answer:
39.2 km/hr.
Step-by-step explanation:
Given,
Mariko distance to work = 72 mile
1 mile = 1.6 Km
72 mile = 1.6 x 72= 115.2 km
time taken to cover this distance = 2.25 hr
Average speed of mariko = 115.2/2.25 = 51.2 km/hr
Issei distance to work= 226 Km
time taken by issei = 2.5 hr
Average speed of issei = 226/2.5 = 90.4 Km/hr
Difference between their average speed
= 90.4 - 51.2 = 39.2 km/hr
Hence, the average speed difference is equal to 39.2 km/hr.
