Answer:
7x - 5
Step-by-step explanation:
Let
Nina = x coins
Clayton = 6x - 5 coins
Expression for the total number of coins Nina and Clayton have altogether.
Nina + Clayton
= x + (6x - 5)
= x + 6x - 5
= 7x - 5
The correct answer and expression is 7x - 5
The information shown here only shows a principal sum, a rate of interest and a period or time. There is no question as to what is needed. But suppose the need is for simple interest, then we calculate using the given information and the formula:
I = PRT
where I is simple interest, P is the principal, R is the rate per year, and T is time
P = 290, T is 6 months which is 0.5 years, R = 12.5 % which is written as 0.125 in decimal fraction.
I = 290 × 0.125 x 0.5 → I = 18.125
Therefore after 6 months , the interest earned will be 18. 125 dollars
