jack and Jill went out to eat. Their bill came to $39.45 before tax. If there was a 6% tax on the meal, how much did it cost in all?

Step-by-step explanation:

To find the % of something simply turn the % (6) to a decimal (.06) then multiply it by 39.45

SO... 39.45 * .06= 2.36

$2.36 is the total tax you'd owe, add that to the meal (39.45+2.36) and you get 41.81

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
