Write an expression so that the product of a whole number and a decimal is.0.28

Let

x-------> the whole number

y------> the decimal number

we know that

------> equation 1

assume the value of x and then calculate the value of y

Let

x=280

solve for y in the equation 1

substitute the value of x

therefore

the expression is equal to

280*0.001=0.28

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

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
