As water evaporates from a bucket, its weight changes at a rate of -1 3/8 ounces per day. Write an equation using exact values to show the change in the bucket's weight after one full week. (One week has seven days.) Be sure to show the total weight change after one week.

Respuesta :

Answer: -9 5/8 or -9.625
Steps: -1 3/8*7

Total change in weight in a week is -9.625 ounce in a week

Given that;

Weight changes per day = -1³/₈ = -11 / 8 ounce

Find:

Equation for rate change

Total change in weight in a week

Computation:

Equation for rate change = Number of days × Weight changes per day

Equation for rate change = [-11/8]n

Total change in weight in a week = 7 × [-11 / 8]

Total change in weight in a week = -9.625 ounce in a week
