The correct answer is (d). If d represents the number of dimes and q the number of quarters, the total number of coins would be <span>d+q</span>, which is given as 40 in the prompt: <span>d+q=40</span>
Since each dime is worth ten cents and each quarter worth twenty-five cents, their total value would be <span>0.10d+0.25q</span> which would total 5.80.: <span><span>0.10d+0.25q=5.80 I HOPE THIS HELPS YOU</span></span>
