Question 1 (1 point)
Ajar contains a quarters and ddimes. There are 7 coins in the jar, and the total value
of the coins is $1.00. Which system of equations can be used to find out how many
of each type of coin the jar has?
0.109 +0.25d = 1.00
q+d=7
0.25 +0.10d = 7,00
q+ d = 1
0.25 +0.10d = 1.00
q+d=7
259 +10d = 1
q+d=7
