Mary had $479.77 in her savings. She did several babysitting jobs and spent $211.45 on clothes, food & concert tickets. Mary now has $268.32 in her savings account. How much money did Mary make babysitting?
Answer provided by our tutors
Let 'x' represent the amount Mary made babysitting, then we add 'x' to the new savings amount:
479.77=268.32+x+211.45
x=0
So Mary did not earn any money babysitting, she simply spent her money on clothes, food and concert tickets.
