Question

Harita must memorize 90 measures of music for her cello solo at a concert. She plans on memorizing 18 new measures for every 3 days of practice. Which equation can be used to determine m, the number of measures Harita still needs to memorize, as a function of d, the number of days of practice since she began learning the piece? Solve for m

Answer 1

We can start with this: \(\boxed{\text{measures left to memorize}} = \boxed{\text{total measures}} - \boxed{\text{measures already memorized}}\)
