I.Activity No. 7: Simply Interesting (15 minutes)II.III.IV.Objectives: Apply the concept of percentage in solving simple interest rate related problemsMaterials Needed: Pen and paperInstructions: Read and solve each word problems involving percentage related to simpleinterest rate.1. How much interest is earned on P6,200 at 4% for one year?2. What was the interest rate if your balance on an investment of P27,750 at the end of sixyears is P41,070?3. At what rate wasvestment made that obtains P2,520 on P10,500 over four years?​

Note: pabrainliest ty :3Answer:1. P2482. 8% per year3. 3.62 per yearSolution:1.Interest = Principal × Rate × TimeP = 6200, R = 4% or 0.04, T = 1 year[tex]6200 \times 0.04 \times 1 = 248[/tex]2.A = Principal + Principal × Rate × TimeA = 41070, P = 27750, Rate = n, Time = 6 yearsInterest = A - P[tex]41070 - 27750 = 13320[/tex]Rearrange to solve for Rate[tex]r = \frac{interest}{p \times t} [/tex][tex]r = \frac{13320}{27750(6)} [/tex][tex]r = \frac{13320}{166500} [/tex][tex]r = 0.8 \: \: \: or \: \: \: 8\%[/tex]3.A = Principal + InterestA = n, P = 12020, Interest = -10500[tex]a = 12020 - 10500 = 1520[/tex]Rearrange to solve for rate[tex]r = \frac{interest}{p \times t} [/tex][tex]r = \frac{1520}{10500(4)} [/tex][tex]r = \frac{1520}{42000} [/tex][tex]r = 0.0362 \: \: \: or \: \: \: 3.62\%[/tex]
