Susan deposits $1,200 in an account that earns 8% simple interest annually. in how many months will susan's account balance reach $1,344? (use the simple interest formula i=prt, where i = interest, p = principal or amount borrowed, r = rate, and t = time in years.)

You need to calculate the interest between the initial amount ($1200) and the final amount ($1344). The difference is $144, this is the interest that you need to gain.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
