define a variable and write an equation for each situation, then solve.
1. chip earns a base salary of $500 per month as a salesman. in addition to the salary, he earns $90 per product that he sells. if his goal is to earn $5k per month, how many products does he need to sell?
2. a pizza shop charges $9 for a large cheese pizza. additional toppings cost $1.25 per topping. heather paid $15.25 for her large pizza. how many toppings did she order?

Chip needs to sell 50 products in order to match his goal.

Heather ordered 5 toppings.

Step-by-step explanation:

1) Let p = the number of products Chip sells

Equation:

Chip needs to sell 50 products in order to match his goal.

2) Let t = the number of toppings on the pizza

Equation:

Heather ordered 5 toppings.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
