Answer 1

Answer:

a) L = 4p

b ) 24 light bulbs

Step-by-step explanation:

Robin is buying energy-efficient light bulbs. Each package of 4 light bulbs costs $13. She has a coupon for $5 off her total purchase.

Each package of 4 light bulbs costs $13.

a.Write an equation to determine the total number of light bulbs, L, for p packages.

1 package = 4 bulbs

L = 4p

Where p = number of packages

b) Then determine the number of light bulbs Robin will get if she buys 6 packages. Show your work.

L = 4p

p = 6 packages

L = 4 × 6

L = 24 light bulbs
