A slice of pizza is $3.20 and a drink is $1. You spent $10.60. Write and solve an equation using “p” number of slices of pizza you bought.

1 answer

The cost of "p" slices of pizza is p * $3.20. Since you also bought a drink for $1, the equation would be:

p * $3.20 + $1 = $10.60

To solve for "p", we can subtract $1 from both sides of the equation:

p * $3.20 = $10.60 - $1
p * $3.20 = $9.60

Finally, we divide both sides of the equation by $3.20 to isolate "p":

p = $9.60 / $3.20
p = 3

Therefore, you bought 3 slices of pizza.
