What is the 60th term 3, 7, 11, 15

243

Step-by-step explanation:

Since this equation starts with 3 and increases by 4 every term we can construct an equation

y = difference * x + initial term

Our initial term is 3 and our difference is 4

y = 4x + 3

Now, we can input 60 for x

60 * 4 + 3 = 240 + 3 = 243

First, multiply to find the total square footage of the counter.

2 ft x 6 ft=12 square feet
2.5 ft x 4 ft=10 square feet
Total square feet of the counter is 22 square feet.

To find the total cost, just multiply the area by the cost per square foot.
$42 x 22=$924
