Question 7 Review

1) Listen

A new bagel store opened. The first day 15 customers entered the store. The number of

customers that enter the store triples each day after. Which function represents f(d), the

number of customers that enter on the d day?

1.

f(d) = 3(15)

2.

f(d) = 3d + 15

3

f(d) = 150 + 3

f(d) = 15(3)

Step-by-step explanation:

Given

--- day 1

-- i.e. triples daily

Required

Determine the function f(d)

The number of customers on a particular day is:

Customers = Day 1 + Rate * Number of days

Represent as a function:

Where d is the number of days.

So, we have:

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76
