Zorluk: OrtaDecimal Operations and Currency Word Problems

A combat medic is restocking his medical kit. He purchases 55 rolls of medical tape for $2.45\$2.45 each and 33 bottles of antiseptic for $4.20\$4.20 each. If he pays with a $50.00\$50.00 bill and there is no sales tax, what is the exact amount of change he receives?

Cevap: 25.15 $

Cevap

25.15
The correct answer is found by calculating the total cost of all items ($12.25+$12.60=$24.85\$12.25 + \$12.60 = \$24.85) and then subtracting that total from the $50.00\$50.00 payment amount to find the change due ($50.00−$24.85=$25.15\$50.00 - \$24.85 = \$25.15).

Adım Adım Çözüm

1
Calculate the total cost of the medical tape.

Calculate the total cost of the antiseptic.
$12.60

3
Add the costs of the tape and antiseptic to find the total purchase amount.
$24.85
12.25+12.25 + 12.60 = $24.85.

50.00−50.00 - 24.85 = $25.15. This is the exact change received.
