Answer:
jt = 33
Step-by-step explanation:
c___j___t
ct= cj+ jt
70 = (7x +2) + (5x+8)
70 = 12x +10
12x = 70 - 10
12x = 60
x = 60/12
x = 5
jt = 5x +8 = 5(5) +8= 25 + 8 = 33
SO; jt = 33
If you want cj ; cj = 7x +2=7(5)+2=35+2=37
I hope I helped you^_^
Notice that the pattern is "previous term plus 2". This is an arithmetic sequence where the difference (d) equals +2
= a₁ + d(n - 1) ; where a₁ is the first term, d is the difference, and n is the term.
f(n) = 1 + 2(n - 1)
f(n) = 1 + 2n - 2
f(n) = 2n - 1
********************************
f(10) = 2(10) - 1
f(10) = 20 - 1
f(10) = 19
First change 2/3 into a decimal: .67. Then divide 30 by .67: 44.77. Round it: 44.77 = 45. Each shirt was $45 :)
