There are 1000 grams in 1 KILOgram.
therefore in 23.24/kg can be just written using grams as 23.24/1000, since 1kg = 1000 g.
so the price of the chicken per gram is then 23.24/1000 or $0.02324 per gram, roughly 2 and 1/3 pennies per gram.
and the turkey is 5.17/250 in grams already, that gives us $0.02068 per gram, which is roughly 2 pennies.
well, their price difference is 0.02324 - 0.02068, which is 0.00256 per gram unit.
since we know there are 1000 grams in 1 Kg, how much is that for 1000 grams or a Kg? 0.00256 * 1000 or $2.56.
Given:
savings 12% of her salary.
savings $4,200
This year's salary: x + 3,000
Last year's salary: x
4,200 represents 12% of her salary.
4,200 / 12% = 35,000 is her salary this year.
x + 3,000 = 35,000
x = 35,000 - 3,000
x = 32,000 her salary last year.
