There were 23 students polled in total 2 students play a sport and play a musical instrument 4 students do not play a sport and do not play a musical instrument 10 students in total play a sport two way graph

Draw a chart that shows the possibilities, fill in the numbers you know (black numbers), then make the totals add up (red numbers). Addition and subtraction is all it takes.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
