Answer:
She shoveled 9 driveways on Sunday
Answer:
Step-by-step explanation:
We know a total of 6000 is being turned into 510, in two accounts which equal to 15%, to find how much is in each account we can create the following equation:
Solve for x
Now multiply x by the corresponding percentages to find how much was invested into each percentage.
Therefore we now know that 170 dollars was invested into the 5% division, and 340 dollars was invested into the 10% division.
We can of course check our answer by adding 170+340 which equals our original investment of 510.
75%=3/4
84/x=3/4
then you cross multiply
84*4=3x
26*4=x
104=x
