Myrna bought 7 more bags of trail mix than candy bars. Therefore, she bought 7 more items of trail mix than candy bars.
To find out how many candy bars Myrna bought, we need to subtract 7 from the total number of items she bought.
Since each candy bar costs $0.80 and each bag of trail mix costs $0.65, the total cost of the candy bars is (0.80 * (number of candy bars)) and the total cost of the trail mix is (0.65 * (number of trail mix bags).
Therefore, the equation to solve would be:
0.80x + 0.65(x+7) = 21.95
This equation simplifies to:
0.45x = 21.95
And then we divide both sides by 0.45 to get the answer:
x = 48.8
Myrna bought 48 candy bars.
