8. Tai put $5,200 in a savings account that pays 4.2% simple interest. Each year she
withdraws the interest and treats herself
to a visit to a spa. How much can she
spend each year?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
