Problem 2 of 25EasierAlgebra Arithmetic

Al gets the disease algebritis and must take one green pill and one pink pill each day for two weeks. A green pill costs

\$1

more than a pink pill, and Al’s pills cost a total of

\$546

for the two weeks. How much does one green pill cost?

Show solution

Solution

Each day’s pills cost

546 \div 14 = 39

dollars. If

x

is the cost of a green pill, then the pink pill costs

x-1,

x+(x-1)=39.

Solving gives

x=20.

Thus, the correct answer is D.
