Answer:
34.65
Step-by-step explanation:
Weight of the box
= 65% / 100% x 21
=0.65 x 21
= 13.65 pounds
21 + 13.65 = 34.65
Answer: 60 pounds
Step-by-step explanation:
Hi, to answer this question we have to multiply the weight of Kiva's father box (x ) by the percentage 1- 0.65/100 , (since the decimal form of 0.65 = 65/100 and 1 is the whole weight of her father's box) . That expression must be equal to the weight of that box that Kiva carries.
Mathematically speaking:
x (1-0.65) =21
x 0.35 =21
Solving for x
x = 21/0.35
x = 60 pounds
