To celebrate the first day of school, Tanvi brought in a tray of caramel brownies and walnut brownies. She brought 45 caramel brownies and 15 walnut brownies. What percentage of the brownies were caramel? Write your answer using a percent sign (%).

45%?

Step-by-step explanation:

38.25

Step-by-step explanation:                                                                                                       To subtract 15 percent from 45 just divide the percentage (15) by 100, subtract this value from 1, then multiply it by the initial value (45), so:

Final Value = 45 × (1 - 15/100)

Final Value = 45 × (1 - 0.15)

Final Value = 45 × (0.85)

Final Value = 38.25

Subtract 15% is the same as discount 15%. this operation could be, for example, a 15% discount on 45.

Note: 0.15 can be found just by moving the decimal point 2 places to the the left 15/100 = 0.15 as a decimal.

answer: yes youre right.
