Answer:
100,000
Step-by-step explanation:
Given :
Initial deposit = 40000
Amount of money = Initial deposit / Reserve rate
When reserve rate = 10% = 0.1
Amount of money = 40000 / 0.1 = 400,000
When reserve rate = 8% = 0.08
Amount of money = 40000 / 0.08 = 500,000
Difference = 500,000 - 400,000 = 100,000
Amount of money will increase by 100,000
x=8

x+2=7x-3
x+7x=3-2
8×= 1
×=8

13y+25=8y+5
13y+8y= 25+5
21y=30
y= 30-21

1. 8 hours 2. 12 pumps
1. 80 ×10=800
there are 800 miles between abuja and lagos
800÷100=8
it will take 8 hours
2. with 3 pumps it takes 36 hours. you need to be 4 times quicker so you need 4 times more pumps.
4×3=12 pumps
2x^7
Multiply
x ^4 by x ^3 by adding the exponents.
Subtract from both sides to get
