Her book was 10 days late. D = days. The equation is .25(4) + .30d = 4.00. First you multiply .25 • 4 to get 1. Then you subtract 1 from both sides and get .30d = 3. Next you divide both sides by .30 to get d = 10.

Answer:

14 days

Step-by-step explanation:

first 4 days= $0.25 x 4 = $1.00

how much money is she left to pay = $4.00 - $1.00 = $3.00

how many days will it take to give the remaining money= $3.00/$0.30=10

so, no of days she borrowed is = 10 +4 =14!!!
