Step-by-step explanation:
solution,
given,
Nikki spent 50% of her money for a shirt.
again she spent 25 % of her money.
here,
50% + 25% = 75%
100% - 75%= 25%
now,
25% = $7
multiplying both sides by 4
25% × 4 = $7 × 4
100% = $28
Her total money is $28
again, 75% of 28
= 75/100 × 28
28
so, she spent $ 28
The total amount of money spent by Nikki on the shirt and the gift given the amount she has left is $28.
The first step is to determine the fraction of the money she has left: 1 - (fraction of the money spent on shirt + fraction of the money spent on gifts)
1 - [1/2 + (1/2 x 1/2)]
= 1 - 3/4 = 1/4
Now, divide $7 by 1/4 : $7 x 4 = $28
