Answer:
The family bought 2 bags of chips
Step-by-step explanation:
Let the number of chips bags be = x
The number of candy bars = twice as much as the number of bags of chip
The number of candy bars = 2x
The total cost spent is = $5.50
Therefore cost of all the chips bags + candy bars = 5.50
2x + x = 5.50
3x = 5.50
x = 
x = 1.83
x = 2 (approx)
Thus the number of chips is 2 and the candy bars is 2(2) = 4 bags
Very handy question to know the answer to. I know of no place on the planet that does not have a tax of some sort.
The tax only applies when money changes hands. It does not apply to any discounts
So if you take the deal, the cost is
Cost of 2 pizzas = normal price - the discount.
Cost of 2 pizzas = 2*10.50 - 2.00
Cost of 2 pizzas = 21 - 2
Cost of 2 pizzas = 19.00 dollars.
Not you add on the sales tax. You can do this one of two ways, the long way or the short way.
<u>Long way</u>
Find the sales tax
Tax = % * cost
Tax = (7.5/100) * 19
Tax = 1.425 don't round yet.
Total Cost = purchase + tax
Total Cost = 19.00 + 1.425 = 20.425 Now round. This is a real problem. It depends on what you have been told to do about rounding when 5 is the last digit. I round up. So my answer would be 20.43 <<<<< Answer.
<u>Short Way</u>
Cost = (Price - discount)*(1 + %/100)
Cost = (21 - 2)*(1+ 7.5/100)
Cost = 19 * (1.075)
Cost = 20.425 = 20.43
