For the answer to the question above,
The simple interest formula is I = P * r * t
P is the principal (2,000)
r is the interest rate (7% or 0.07)
t is the time (5)
2000 * 0.07 * 5 = 700
$700.00 is the interest
Joe has to pay $700.00 in interest.

Answer:
9.08 hours
Step-by-step explanation:
in order to fill 1 pool
fill rate by pipe = 1 pool / 15 hours = 1/15 pool per hour
fill rate by hose = 1 pool / 23 hours = 1/23 pool per hour
combined rate = fill rate by pipe + fill rate by pool
= 1/15 + 1/23 = 38/345 pool per hour
since:
38/345 pool -----------> will take 1 hour
1 pool --------------------> will take 1 hour x (345/38) = 9.08 hours
Answer:
58.3333
Step-by-step explanation:
make 14/24 into a fraction with a denominator of 100, and you get 58.333333 over 100
Total number of units = q
Cost of each unit = 100/q + 7
Total cost of q units = q(100/q +7) = 100+7q
To make revenues greater than $8,000
8000<100 +7q
8000-100 < 7q
7900<7q
q>7900/7
q>1128.58
q>1129 units
Therefore, the minimum number of units sold must be greater than 1129 units.
