and
to get 975 girls. Do the same for 6. For 7, it says that the television is $550, and it is only 55% of her savings. Therefore, to find her original amount, you will put 550 in the numerator and x in the denominator, and cross multiply 55/100 to get 1000. For 8, do the same thing, and put 354 for the numerator, x for denominator, 75/100 and cross multiply.
