just olya [345]

Answer:

241904.9483

≈ 241905

Step-by-step explanation:

Given that,

current amount of house = 180,000

value of the home increases at a rate of 3% per year

To find,

approximate value of the home after 10 years using exponential function

<h2>Equation</h2><h2>a(1 + r)^t</h2>

where a is the amount of house = 180,000

r is the interest rate per annum = 3% = 3/100 = 0.03

t is the number of years = 10

180,000 (1+0.03)^10

180,000 (1.03)^10

241904.9483

≈ 241905

13. For a party, Bob's Pizza charges $12 for each
marusya05 [52]

The number of pizzas you must order for the price to be the same is 5

<h3>How many pizzas must you order for the price to be the same?</h3>

Bob's Pizza charges = $12 for each supreme pizza

This can be represented as

y = 12x

For Mike's Pizzeria, we have

y = 8x + 20

Substitute y = 12x in y = 8x + 20

12x = 8x + 20

Evaluate the like terms

4x = 20

Divide by 4

x = 5

Hence, the number of pizzas you must order for the price to be the same is 5
