Question

The expression 2.5 + 2t gives the cost, in dollars, of t tulips at a flower store. Joanna has $14.00.
How many tulips can she afford to buy?

Answer 1

Answer:

5 tulips.

Step-by-step explanation:

Given:

The expression for the cost of the tulips is $Cost=2.5+2t$

Where, $t$ is the number of tulips.

Now, Joanna has $\ 14.00$.

So, number of tulips that can be bought with the above amount can be obtained by substituting $\ 14.00$ for cost. This gives,

$Cost=2.5+2t\\14=2.5+2t\\2t=14-2.5\\2t=11.5\\t=\frac{11.5}{2}=5.75 \approx 5$.

As the number of tulips cannot be in decimals or fractions, so the maximum number of tulips that can be bought will be 5.
