Each month, kaisorn deposits $50.00 onto her public transportation card. it costs her $2.50 per trip to ride the subway. thom deposits $40.00 on his public transportation card. it costs him $2.00 per trip to ride the subway. if x represents the number of trips and y represents the amount remaining in each account, which system of equations represents their transportation costs? 50 − 2.5x = y 40 − 2x = y 50 + 2.5x = y 40 + 2x = y 50 − 2.5y = x 40 − 2y = x 50 + 2.5y = x 40 + 2y = x

For Kaisorn:

For Thom:

Step-by-step explanation:

Each month, Kaisorn deposits $50.00 onto her public transportation card.

It costs her $2.50 per trip to ride the subway. Means 2.50x

Thom deposits $40.00 on his public transportation card. It costs him $2.00 per trip to ride the subway. Means 2x

Let x represents the number of trips

Let y represents the amount remaining in each account.

Then the system of equations represents their transportation costs are :

For Kaisorn:

For Thom:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
