Answer:

$ 1249.6

Step-by-step explanation:

given,

cost of saddle = $534.00

riding chaps cost  = $87.02

boots cost = $143.99

hat cost = $55.87

pairs of glove cost = $15.94

sales tax paid = 7.5%

Sam's lesson cost =  $35.00 per  lesson

number of lesson = 10

Total purchase cost

= $534.00 + $87.02 + $143.99 + $55.87 + $15.94

= $ 836.82

cost included sales tax

= 1.075 x $ 836.82

= $ 899.58

Cost of lesson = 10 x $35.00 = $350.0

Total cost of the Sam

= $ 899.58 + $350.0

= $ 1249.58

= $ 1249.6

What's the answer to this ? Question
AURORKA [14]
The answer is 10/14

How: 7 is half of 14 so 14 would be the denominator which is the bottom number. So what would 5 be half of? (think of 5+5) It's 10! So 10 would be the numerator which is on the top making the fraction 10/14.
Hope this Helps!
