Caleb earns points on his credit card that he can use towards future purchases. he earns four points per dollar spent on flights, two points per dollar spent at hotels, and one point per dollar spent on all other purchases. last year, he charged a total of $9,480 and earned 14,660 points. the amount of money spent on flights was $140 more than twice the amount of money spent on hotels. find the amount of money spent on each type of purchase.

Points are earned as:

Total money spent on credit card last year = $9,480

Total points earned through credit card last year = 14,660 points

Money spent on flight = 140 + 2 × Money spent on hotels

Let money spent on flights be 'a', money spent on hotels be 'b' and money spent on other things be 'c'

⇒ Total money spent on credit card last year = a + b + c = 9,480 (i)

And, Total points earned through credit card last year = 4×a + 2×b + c = 14,660 (ii)

Also, a = 140 + 2×b (iii)

Substitute (iii) in (i) and (ii)

(i): 140 + 2b + b + c = 9,480

⇒ 140 + 3b + c = 9,480

⇒ 3b + c = 9,340 (iv)

(ii): 4×(140 + 2b) + 2b + c = 14,660

⇒ 560 + 8b + 2b + c = 14,660

⇒ 10b + c = 14,100 (v)

Subtracting (iv) from (v)

7b = 4,760

⇒ b = 680

Substituting value of b in (iii)

a = 140 + 2×680

⇒ a = 1,500

Substituting value of 'a' and 'b' in (i)

1,500 + 680 + c = 9,480

⇒ c = 7,300

Hence, Caleb spent $680 on flights, $1,500 on hotels and $7,300 on other purchases

yo answer should be 6 if im not mistaken

step-by-step explanation:

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
