3. The employee at a local coffee shop knows that during their morning rush, 7 out of every 15 people who buy coffee will also buy a muffin. They use this fact to make sure they bake enough muffins. If they
are expecting 300 customers in the next few days, how many muffins will they need to have prepared?

7 out of 15 is 46% and 46% times 300 is 138. Therefore, the answer is 138 muffins.

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
