Jesse bought a $340$340​ -gram bag of ground coffee. He uses $18.75$18.75​ grams of ground coffee each day. When there are $40$40​ grams of ground coffee remaining in the bag, Jesse will buy another bag to make sure he doesn't run out of coffee.

Part A
Use the drop-down menus below to create an equation that represents the situation, in which $d$d​ represents the number of days until Jesse buys another bag of ground coffee.

Respond in the space provided.

If your test is on paper, write your answer on the answer sheet.

Answer 1

He can use the $340$-gram bag of ground coffee for $17$ days before he buys a new bag.

This can be found by solving the equation:

$18.75d = 340 - 40$

$18.75d = 300$

$d = 300/18.75 = 16$

Since we can't have a fraction of a day, he can use the bag for $17$ days.
