Fraction form 3/2 or 1.5 in decimal form :)
-3 subtract the perenthesis (-1) equal to -2
B: 4.75+0.75n ≥25
Because she has already spent 4.75 and she only has $25 and she cannot spend more than$25
10, because 10 does not need to be rounded to the nearest 10 if the number is already 10, but if the number was 17 then rounding to the nearest 10 would be 20
Box A is 4. 4 is 5% of the total boxes.
5% = 1/20, so multiply whatever number that's 5% of the total by 20 to get the total.
4 x 20 = 80.
There are 80 marbles total.
Hope this helps!
