In a certain clothing store, 4 shirts and 6 ties cost $70, and 2 shirts and 4 ties cost $42. what is the cost of each tie?

$7

$12

$18

Each tie would cost $7

(s=each shirt t=each tie)

4s+6t=70

2s+4t=42

6•7=42

70-42=28

28/4=7

4•7=28

42-28=14

14/2=7

Each tie costs $7 and each shirt also costs $7.

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
