What is the simple interest rate on a $2300 investment paying $906.20 interest in 19.7 years?

2%

Step-by-step explanation:

Given data

Principal=$2300

Simple interest=$906.20

Time= 19.7years

Required

The rate in percentage

We know that

SI=PRT/100

substitute

906.20=2300*R*19.7/100

906.20=45310R/100

cross multiply

906.20*100= 45310R

90620= 45310R

R= 90620/45310

R=2%

Hence the rate is 2%

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
