Step-by-step explanation:
If she travels by air, she will be able to work seven hours in D.C. work four hours once there. Her expected income from each hour of work in D.C. is $40. This means that the total amount that she earns in 7 hours would be
40 × 7 = $280
if she drives, she will only have time to work four hours once there. This means that the total amount that she earns in 4 hours would be
40 × 4 = $160
The difference in both amounts would be
280 - 160 = $120
she will chose to fly if and only if the price differential (air cost minus driving cost) is less than $120
Answer:
5.3 ft
Step-by-step explanation:
Because CD corresponds to BC, the scale factor from triangle ABC to triangle CDE, is 7/8. Now, DE corresponds to AB, so to get DE, we must multiply the value of AB by 7/8. 6 times 7/8 is 5.25, and rounding to the nearest tenth of a foot, the value of DE is 5.3.
Hi there.
Since she reads 15 pages in 2 hours, all we have to do to find out how much she reads in 1 hour is divide.
15/2 = 7.5
7.5 pages/hour
Same applies to the pay
40/2 = 20
$20/hour
Karyn proofreading rate is 7.5 pages per hour. Karyn receives on average $20 per hour.
