Question

Ingrid is buying a pair of pants with an original cost of c dollars. The pants are on sale for 15% off their original cost. Which tow calculations could Ingrid perform in order to find the amount she needs to spend.

Answer 1

Given data:

c is the original cost

Sale for 15% off

To find the amount she needs to spend Ingrid needs to calculate the 15% of the original cost (by multiplying the original cost c by 0.15), and then subtract it from the original cost:

`c-0.15c`
