G = 1.25m + 5
n = 1.50n + 1
g = n

1.25m + 5 = 1.50m + 1 <== ur equation
5 - 1 = 1.50m - 1.25m
4 = 0.25m
4 / 0.25 = m
16 = m <== mary has 16 <==

g = 1.25m + 5....g = 1.25(16) + 5....g = 25 <==Gracie has 25 <==
n = 1.50m + 1...n = 1.50(16) + 1.....n = 25 <==Nancy has 25 <==

You are at a grocery store and the cost of your groceries is $32.75. You need to add the sales tax, which is 6%. You have one $2
schepotkina [342]

1. The total bill including sales tax is <u>$34.72</u>.

2. The amount the purchaser should pay the cashier is <u>$34.72</u>.

3. The denominations for the payment should be one $20 bill, one $10 bill, four $1 bills, and 72 cents (pennies).

<h3>How is the total cost determined?</h3>

The total cost payable to the grocery store cashier is the cost of the groceries plus the sales tax.

The cost for groceries = $32.75

Sales tax = 6%

Total cost = cost plus sales tax

= $34.72 ($32.75 x 1.06)

We can check the sum as follows:

Unit  Bill  Amount

1      $20    $20

1      $10       10

4       $1        4

Cents           0.72

Total        $34.72

Thus, the grocery purchaser will be spending <u>$34.72</u>, including the sales tax.

Martha biked 55 miles per day and Enrico biked 145 miles every 3 days. After 6 days, which statement correctly compares the numb
masha68 [24]

Answer:

After 6 days Martha biked 330 miles, while Enrico biked 290 miles.

Step-by-step explanation:

i. Martha bikes 55 miles per day.

So that after 6 days, Martha would have covered;

55 miles x 6 = 330 miles

After 6 days, Martha would have biked 330 miles.

ii. Enrico bikes 145 miles every 3 days.

Then after 6 days, Enrico would have covered;

\frac{6 days}{3 days} x 145 miles

= 2 x 145 miles

= 290 miles

After 6 days, Enrico would have biked 290 miles.

After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
