The bus fare in a city is People who use the bus have the option of purchasing a monthly coupon book for With the coupon book,

SashulF [63]

Answer:

26 times

Step-by-step explanation:

The question has missing details. However, the given parameters are

Given

Without Coupon

Bus Fare = $2.00

With Coupon

Coupon = $39.00

Bus Fare = $0.50

Represent the number of fares with x

Without Coupon, cost of fares is

Cost = 2x

i.e.

f(x) = 2x

With Coupon, cost of fares is

Cost = 39 + 0.5x

i.e.

g(x) = 39 + 0.5x

To calculate when both fares will be equal, we must have:

f(x) = g(x)

2x = 39 + 0.5x

Collect like terms

2x - 0.5x = 39

1.5x = 39

Solve for x

x = 39/1.5

x = 26

This implies that, for both cost to be equal, the person must go 26 times

I have one dozen eggs and I discover hot only 1/3 of the broken and I need use 1/6 how many I have left

zhenek [66]

Answer:

$X=2$

Step-by-step explanation:

From the question we are told that:

Total eggs $n=12$

Broken eggs $n_b=1/3n=4$

Used eggs $n_u=1/6n=2$

Generally the equation for amount of eggs left X is mathematically given by

$12=X+n_b+n_u$

$12=X+4+2$

$X=\frac{12}{6}$

$X=2$

alekssr [168]

Answer:

Step-by-step explanation:

Given

Joaquin's score is $75,72,85,62,58,91$

and Trisha's score is $92,90,55,76,91,74$

Arranging score in order of value we get

Joaquin's : $58,62,72,75,85,91$

Trisha's : $55,74,76,90,91,92$

as no of values is even therefore their median is

Joaquin's $=\frac{72+75}{2}=73.5$

Trisha's $=\frac{76+90}{2}=83$

Therefore median of Joaquin's is lower

Thus Joaquin wins the game
