Question

The cost of the toy is expressed by the function y = 3x + 5, where x is the number of toys. If Peter bought 8 toys, find the cost of the toys.

Answer 1

$29

Explanation:

To find the cost of the toys when Peter bought 8 of them, we can substitute the value of x = 8 into the given function: y = 3x + 5

Plugging in x = 8:

y = 3(8) + 5

y = 24 + 5

y = 29

Therefore, when Peter bought 8 toys, the cost of the toys is $29.

Answer 2

y=29

Explanation:

y=3(8) + 5

y=24+5

y=29
