Answer:
Step-by-step explanation:
b) Diameter of Mercury = 4.88 * 10³ = 4.88 * 1000 = 4880 km
Radius of Mercury = 4880÷ 2 = 2440 km
c) Mass of Jupiter = 1.898 * 10²⁷ = 18.98 * 10²⁶
Mass of Saturn = 5.68 * 10²⁶
Difference = 18.98 * 10²⁶ - 5.68*10²⁶
= (18.98 - 5.68) * 10²⁶
= 13.30 * 10²⁶
= 1.330 * 10²⁷
Answer:

Step-by-step explanation:

The answer is A $525
He earns $300 a week
The sales for one week are $2500
Percentage of commission on sale above $1000= 15%
[2500-1000]*(15/100)
=1500*(15/100)
=15*15 dollars
=$225
Then Gross pay of Edgar Anderson for the week = (300+225)dollars
=$525
