Answer:

y = 0.75x + 12

Step-by-step explanation:

y: total cost

x: number of batteries

If the toy costs $12, the total cost must be those $12 plus the amount of money spent in the batteries.

Money spent in batteries:

0.75x

this is because each battery costs $0.75, is he uses x amount of batteries he must pay the 0.75x

Thus, the total cost is

y = 0.75x + 12

which is the cost of the batteries and the cost of the toy added together.

puteri [66]
In order to determine the number of boys in the class, first, we set-up an algebraic equation. Let x = number of boys in the class. The equation is then: x + 4x = 45. This is because the number of girls is 4 times greater than the number of boys. After solving the algebraic equation, it is then determined that there are 9 boys in the Chemistry class.
