A display case of friendship rings are marked 5 for $1.00. If Zach wants to buy 50 friendship rings, how much will Zach spend (not including tax)?

$10, 50 / 5 = 10 so $10

To calculate the amount Zach will spend on buying 50 friendship rings, we need to determine the cost of a single friendship ring.

According to the information provided, a display case of friendship rings is marked 5 for $1.00. To find the cost of a single friendship ring, we divide the total cost by the quantity.

Cost of 5 friendship rings = $1.00
Therefore, the cost of 1 friendship ring = $1.00 / 5 = $0.20

Now that we know the cost of a single friendship ring, we can calculate the total cost for 50 friendship rings by multiplying the cost per ring by the quantity of rings.

Total cost for 50 friendship rings = $0.20 * 50 = $10.00

Therefore, Zach will spend $10.00 on buying 50 friendship rings, not including tax.

To find out how much Zach will spend on 50 friendship rings, we need to calculate the cost per ring and then multiply it by the number of rings.

The display case states that the rings are marked as 5 for $1.00. This means that for every 5 rings, the cost is $1.00. We can divide $1.00 by 5 to find the cost of one ring.

$1.00 ÷ 5 = $0.20

So, the cost of one friendship ring is $0.20.

Now, we can calculate how much Zach will spend by multiplying the cost per ring by the number of rings he wants to buy.

$0.20 × 50 = $10.00

Therefore, Zach will spend $10.00 on 50 friendship rings.
