A student is attempting to isolate the variable t in the literal equation below. Which statement best applies to the sample mathematical work shown? Given: 2t + s – 4 =8 – s
Step 1: I first add 4 to both sides, resulting in 2t + s = 12 – s.
Step 2: I then subtract s from both sides, resulting in 2t = 12 – 2s.
Step 3: I then divide both sides by 2, giving a final answer of t = 6 – s.
A. the student failed to add the proper quatity in step 1
B. the student failed to subtract 2s properly in step 2
C. the student failed to divide both sides by 2 properly in step 3.
D. the mathematical work is correct as written.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

answer4 to the second power is 16

and 4 to the third power is 64,
