To know the percentage of carbohydrates that Osvoldo ate from grains with respect to the total, we simply have to divide the amount of carbohydrates he got with the grains by the total

55 / 220 = 0.25

then to express it as a percentage this number has to be multiplied by 100

0.25 * 100 = 25%

Osvoldo wanted to reach 30% and only got 25%

25% < 30%

Kayla buys two pairs of jeans for j dollars each and one shirt for 15 dollars. she has 60 dollars to spend. The equation 2j+ 15-

weeeeeb [17]

Kayla buys two pairs of jeans for j dollars each and one shirt for 15 dollars. The cost of one pair of jeans is $22.5 (twenty-two dollars and fifty cents)

From the given information

Let the cost of two pairs of jeans be 2j
The cost of 1 shirt = 15
Total amount to spent = $60

∴

The equation is said to be expressed as:

2j + 15 - 60 = 0

Collect like terms

2j = 60 - 15
2j = 45

Divide both sides by 2

$\mathbf{\dfrac{2j}{2}= \dfrac{45}{2}}$
j = 22.5

Therefore, we can conclude that the cost of one pair of jeans is $22.5 (twenty-two dollars and fifty cents).
