Divide 45 in the ratio 7:8

21 : 24

45 ÷ 15 = 3 ← value of 1 part of ratio, thus

7 parts = 7 × 3 = 21

8 parts = 8 × 3 = 24

45 divided in the ratio 7 : 8 is 21 : 24

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
