A baker can make 120 cupcakes in 2 hours. At that rate, how many cupcakes can he make in 3.5 hours? *
Valentin [98]

Answer:

210

Step-by-step explanation:

first I took 120 and divided by four to show how many cupcakes he can make in thirty minutes (.5 of an hour). this was 30. the reason we divided by four is because in two hours theres four halves.

120÷4=30 for half an hour

30x2=60 this is how many cupcakes he can make in one hour

since we already know how many he makes in two hours we're going to use that

120+60=180 (three hours)

120+60=180 (three hours)180+30 (half an hour) =210

joey wants to buy $4,000 vehicle with 10% down for three years at 12% interest. What will his monthly payment be?
Nataly [62]

Answer:

$119.57

Step-by-step explanation:

We have to find present value of annuity to find the monthly payment.

Given,

Present value, PV = $4,000

Down payment = $4,000 × 10% = $400

Remaining present value = $(4,000 - 400) = $3,600

Interest, i = 12% = 0.12

As we need monthly payment, the interest rate will be monthly = 0.12/12 = 0.01.

Number of period, n = 3

monthly payment, m = 12

We know,

Present value of annuity = PMT × \frac{1 - (1 + \frac{i}{m})^{-n*m} }{\frac{i}{m} }

$3,600 = PMT × \frac{1 - (1 + \frac{0.12}{12})^{-3*12} }{\frac{0.12}{12} }

or, $3,600 = PMT × 30.1075

or, PMT = $119.57

Monthly payment should be $119.57
