Increase = $3.15
Answer: 20 days
Step-by-step explanation:
Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:
= 15% × 40
= 0.15 × 40
= 6
6 sales out of every 40 calls per day.
The number of calls to make 120 sales will be:
= 15% of x = 120
0.15 × x = 120
0.15x = 120
x = 120/0.15
x = 800 calls
Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:
= 800/40
= 20 days
Answer:
simultaneous linear equations
Step-by-step explanation:
y=7x+3
y=x-3
Logb1=0 log b 1 = 0 . This follows from the fact that b0=1 b 0 = 1 .
logbb=1 log b b = 1 . This follows from the fact that b1=b b 1 = b .
logbbx=x log b b x = x . This can be generalized out to logbbf(x)=f(x) log b b f ( x ) = f ( x ) .
