Question

Bryn's Grandpa is always creating math problems for her to solve.
In one problem, he gave her a store receipt that listed 72 identical items, each the
same price, for a total cost of
$ * 67.9*
Bryn's Grandpa covered the first and last digits of the total price on the receipt
with stars.
Determine the values of the digits that Bryn's Grandpa covered.

Answer 1

Answer:

The first covered digit = x = 3

The last covered digit = y = 2

The total price on the receipt = $367.92

Step-by-step explanation:

From the above question,

He gave her a store receipt that listed 72 identical items, each the same price, for a total cost of $ * 67.9*

We have to look for multiples of 72

9 × 8 = 72

Let

the first covered digit be represented by x

the last covered digit be represented by y

Step 1

We find the last covered digit

For a number to be divisible by 8,

It must be a multiple of 8

From price:

The last 3 digits =

79* =

We create number in multiples of 8

7.9* = 7.20 + 0.64+ 0.08

7.9* = 7.92

Hence, the last digit is 2

Step 2

We find the first covered digit.

For a number to be divisible by 9, if it is a multiple of 9

The first digit = x is determined as:

= x + 6 + 7 + 9 + 2

= x + 24

= x + 24

The multiple of 9 closet to 24 is 27

Hence,

27 = x + 24

x = 27 - 24

x = 3

Therefore,

The first covered digit = x = 3

The last covered digit = y = 2

The total price on the receipt = $367.92
