Gail has eight united states coins. Their total value is 93 cents. What coins does she have?

Kryger [21]

8 coins = $0.93

3 quarters = $0.75
1 dime = $0.10
1 nickel = $0.05
3 pennies = $0.03

3 + 1 + 1 + 3 = 8 coins

$0.75 + $0.10 + $0.05 + $0.03 = $0.93

A performer expects to sell 5,000 tickets for an upcoming concert. They want to make a total of $311, 000 in sales from these ti

Annette [7]

The price of one ticket is $ 62.2

<h3><u>Solution:</u></h3>

Given that a performer expects to sell 5000 tickets for an upcoming event

They want to make a total of $ 311, 000 in sales from these tickets

<em><u>To find: price of one ticket</u></em>

Let us assume that all tickets have the same price

Let "a" be the price of one ticket

So the total sales price of $ 311, 000 is obtained from product of 5000 tickets and price of one ticket

$\text {total sales price }=5000 \times \text { price of one ticket }$

$311000 = 5000 \times a\\\\a = \frac{311000}{5000}\\\\a = 62.2$

Thus the price of one ticket is $ 62.2
