At the start of the week, Crystal’s bank account had a balance of $280. Each day from Monday to Friday, she used her debit card to pay $5 for parking. She wrote a check for $42, and made two deposits of $75 each. She also withdrew $200 in cash at an ATM. Which of the following expressions can be used to find the balance in Crystal’s account? Select all that apply.
280 + 5(5) + (–42) + 2(–75) + (–200)
280 + 5(–5) + (–42) + 2(75) + (–200)
280 + 5(–5) – 42 + 2(75) – 200
280 + 5(–5) – 42 + 2(–75) – 200

B and C

Step-by-step explanation:

They are the same problem. Both work out.

B 280 + 5(–5) + (–42) + 2(75) + (–200)

C 280 + 5(–5) – 42 + 2(75) – 200

280 + 5(–5) + (–42) + 2(75) + (–200)

280 + 5(–5) – 42 + 2(75) – 200

280 + 5(–5) – 42 + 2(–75) – 200

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
