Question

Isabella has a summer job working for a biologist studying a type of flower. Isabella's job is to collect these flowers from a local park. The biologist pays Isabella $48 per flower and a weekly base salary of $140. Last week, Isabella earned $572 from the biologist. Write an equation for Isabella's earnings last week.

Use f for the number of flowers, and write your equation in the form pf + q = r, where p, q, and R are numbers.

Now use your equation to calculate the number of flowers Isabella collected last week.

Answer 1

48f + 140 = 572

9 flowers

Explanation:

Isabella gets a fixed payment of $140 per week and in addition to that, she gets $48 per flower that she delivers to the biologist.

In the last week, Isabella earned $572 from the biologist.

If she delivers f numbers of flowers to the biologist then the equation of Isabella's earning will be

48f + 140 = 572 ......... (1)

Now, solving this equation (1), we get 48f = 432, ⇒ f = 9

Therefore, she collected 9 flowers last week. (Answer)
