A student put $1,200 in a savings account paying simple interest of 4.5% per year. Find the total amount of the student's savings after 5 years. A: $700. B: $1470. C: $1000. D: $400

(B) $1470

Step-by-step explanation:

Given that the principal initial amount, p=$1200

Rate of simple interest per year, r=4.5% = 0.045

Time, t=5 years

Interest after 5 years,

I=prt= 1200 x 0.045 x 5 = 270

Total amount = Principal initial amount + Interest

=1200+270=1470

So, the total amount of the student's savings after 5 years is $1470.

Hence, option (B) is correct.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
