Answer:B
Step-by-step explanation:
Its B because is a situation where we note the rate at which the number of population was changing before the study
It is (1,15). I recommend using a website called desmos because it helps with graphing.
Answer:
1. $ 0.15 increases for each dollar.
2. There is $ 0.20 increases for each dollar in the 20% column .
3. $ 48.75 is calculated for $325.00 in the 15% column.
$ 65 tip will be calculated in the 20% column for $ 325
Step-by-step explanation:
a. The tip for each dollar would be
= $ 1 * (15%)
= $ 1 * 15/100
= $1 * 0.15
= $ 0.15
Therefore $ 0.15 increases for each dollar.
b. The tip for each dollar would be
= $ 1 * (20%)
= $ 1 * 20/100
= $1 * 0.20
= $ 0.20
There is $ 0.20 increases for each dollar in the 20% column .
c. The $ 325 bill can be broken down into
$ 100+ $100 + $100 +$25
The tip can be calculated
$ 100 * 15%+ $100* 15% + $100* 15% +$25* 15%
= $ 15+$ 15+$ 15+ $3.75
= $ 48.75
The tip can be calculated
$ 100 * 20%+ $100* 20% + $100* 20% +$25* 20%
= $ 20+$ 20+$ 20+ $5
= $ 65
$ 65 tip will be calculated in the 20% column for $ 325.
