Janet wants to calculate the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest. What equation can she use?

Step-by-step explanation:

Given the amount invested for a particular period of time at an interest rate, the equation that can model the Interest achieved on investment is expressed using the simple interest formula as shown;

Simple Interest = PRT/100 where;

P is the principal (amount invested)

R is the rate (in %)

T is the time (in years)

From the equation I = PRT/100, we need to express tht time T as a function of the rest of the variable as shown;

I = PRT/100

cross multiply

100I = PRT

Divide both sides by PR

100I/PR = PRT/PR

100I/PR = T

Hence the the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest is expressed as

T = 100I/PR

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

d.) yes, because the volume of the cone is greater than the volume of the sphere
