Well, honey, let's do some basic math here. 10 quarters are worth 25 cents each, so that's 250 cents total. And 2 dimes are worth 10 cents each, adding another 20 cents to the pot. So, in total, you've got 270 cents. Easy peasy lemon squeezy!
85 dimes = 85*10 cents = 85*10/25 quarters = 34 quarters.
10 quarters = 250 cents (25 x 10) 7 dimes = 70 cents (7 x 10) 250 + 70 = 320 10 quarters and 7 dimes equal 320 cents. In other words, $3.20 or 3 dollars and twenty cents.
4 quarters=10 dimes x quarters=85 dimes quarter=10/4 dimes x (10/4 dimes) = 85 dimes x= 85 dimes/(10/4 dimes) x=34 Answer: 34 quarters
80 cents
To make $2.50 from quarters (worth 25 cents) and dimes (worth 10 cents), we can set up a system of equations. Let q represent the number of quarters and d represent the number of dimes. The equations would be 25q + 10d = 250 (representing the total value in cents) and q + d = 25 (representing the total number of coins). Solving these equations simultaneously, we find that there are 6 ways to make $2.50 using quarters and dimes.
