A car moving at a constant speed travels 88 feet in 2 seconds. Use a proportion to find how many feet it travels in one minute?

88 : 2 ::  x : 60   proportion

(88)(60) = 2x     product of means extremes

5280 = 2x          multiply

264 = x              divide both sides by 2

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

3 is greater then both of those numbers
