Question

Brenda has four more nickels than quarters in her purse. She has a total of $3.80 in change and a $200 in Nordstrom gift cards. How many nickels does she have? ASAP

Answer 1

• 16 nickels

Explanation:

Given

• Nickel n = 5 c
• Quarter q= 25 c
• Total change = $3.80 = 380 c
• n = q + 4

Solution

• 5n + 25q = 380
• 5(q + 4) + 25q = 380 ⇒ substitute n with q + 4
• 5q + 20 + 25q = 380
• 30q = 360
• q = 360/30
• q = 12
• n = q + 4 = 16

12 quarters

16 nickels
