A phone plan has a limit of $25 that can be spent on text messages. The base cost of the text plan will cost a user $5. Each text will cost $0.05. How many text messages (t) can a user send without exceeding the plan limits?

t ≤ 400
t < 400
t ≤ 600
t < 600

supie · Answer

You get $5+0.05t≤25$

supie · Answer

We have to solve for $t$

supie · Answer

We have to Simplify: $-5$, both sides: Then divide both sides by $0.05$ using a fraction bar. fractions is division

supie · Answer

$0.05t+5≤25$

-5: 
$0.05t+5−5≤25−5$
$0.05t≤20$

÷0.05
$\LARGE \frac{0.05t}{0.05}≤\frac{20}{0.05}$

$t≤?$
