Define the variables: a is the number of apples I can buy g is the number of grapefruits I can buy.
Write the equation: 15 = 0.50a + 2g
Answer: Unit price = 0.2 per ounce
Step-by-step explanation:
What we were given;
Product price = $4
Quantity of product = 20 ounce
To get the unit price of the strawberry jam,
We simply devide the product price by the quantity of the product
Therefore;
Unit price = 4 / 20
Unit price = 0.2 per ounce
Let the 1st number be x; 2nd number be y; 3rd number be z.
x + y + z = 79
x = number we are looking for.
y = x * 5 ==> 5 times the first
z = x + 16 ==> 16 more than the first
Therefor,
x + (x * 5) + (x+16) = 79
1st step, multiply the 2nd number: x * 5 = 5x
x + 5x + x + 16 = 79
Add all like numbers:
7x + 16 = 79
To get x, transfer 16 to the other side and change its sign from positive to negative.
7x = 79 - 16
7x = 63
To get x, divide both sides by 7
7x/7 = 63/7
x = 9
To check. Substitute x by 9.
x + (x * 5) + (x+16) = 79
9 + (9 * 5) + (9 + 16) = 79
9 + 45 + 25 = 79
79 = 79 equal. value of x is correct.
C equals 17.5 you have to cross multiply to find what c is equal to
Larissa: y = 250 - 25x
Chucho: y = 30 +30x
