Question

Jennifer stops at Tim Hortons before work to buy coffee and donuts for her and her co-workers. After buying 5.00 worth of donuts and all her coffees at 1.29 each, her total was 11.45. How many coffees did she purchase?

Answer 1

Answer:She purchased 5 coffees

Explanation:

$5.00+$1.29c=$11.45

Subtract $5.00 on both sides:

$5.00-$5.00+$1.29c=$11.45-$5.00

$1.29c=$6.45

Divide 1.29 on both sides:

1.29c/1.29=6.45/1.29

c=5 coffees
