Q:4A ($30) * 0.85 = $25.50

Q:4B ($18) * 0.85 = $15.30

Q:4C ($24.80) * 0.85 = $21.08

Q5:

(For six pack): $2.10 (each) * 8 = $16.80

(For eight pack): 3.12 (each) * 6 = $18.72

8 of the 6 packs would be the better deal.

Q6 (A): Elena is 142.24 cm tall.

(Formula is multiply the inches by 2.54. So, 56 times 2.54 is 142.24)

Q6 (B): Elena is 1.4224 meters tall.

(Formula is divide inches by 39.37. So, 56 divided by 39.37 is 1.4224)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

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
