Normal cost of bagel = x

normal cost of 12 (a dozen) bagel = 12x

After discount the price of one dozen bagel = 12x - 1.4

Total Bagels bought = 56 = 4 dozen and 8 bagel

i.e. Total cost = 4*(12x - 1.4) + 8x

also, total cost of 56 bagel = 0.9*56

i.e. 4*(12x - 1.4) + 8x = 0.9*56

i.e. 56x - 5.6 = 0.9*56

i.e. 56x = 56

i.e. x = 1

Answer: Option A

Cost of 1 bagel is x
Discount of $1.40 is given when 12 bagels are purchased
Bagels bought 56 and cost of each bagel came out to be 90 cents = .90
Therefore,
56(.90) = 56x -4(1.40)
50.4+ 5.6 = 56x
56 = 56x
x = $1.00

A is the correct answer

Archit3110

Dollar and Cents conversion is expected of us so we MUST know this.

Use of terms like pennies, quarters and dimes are unexpected.

Conversion of units such as yard to feet, pound to ounces, miles to kilometers will always be given in question

Similarly Conversion of Hours in to minutes, minutes into seconds, Feet into inches is expected of us so we should know it.

A few unit conversion for helps is as follows


1 Dollar = 100 cents
1 penny = 1 cent
1 Dime = 10 cents
1 Quarter = 25 cents
1 Nickel = 5 cents

1 yard = 3 feet
1 Pound = 16 Ounces
1 Mile = 1.6 Km = 5280 feet
