Since this equation is already in standard form, there is no need to convert it. Standard form is Ax + By = C. In this equation, 7 = A, 3 = B, and 10 = C. From standard form, Ax + By = C equals negative A over B.
7x + 3y = 10
↓
Then you'd simplify.
The slope cannot be simplified any more, so this would be the final answer.

Answer:
450 ounces
Step-by-step explanation:
We know that the cost of the mixture must be the cost of the everyday moisturizing lotion
plus the cost of the self-tanning lotion
, which means
.
The cost of any substance will be the cost per ounce of the substance (c), multiplied by the number of ounces (n), which means C=nc, so we have from the previous formula that we have:
But we also know that the number of ounces of the mixture must be the sum of the number of ounces of the everyday moisturizing lotion with the number of ounces of the self-tanning lotion, so we have
We want to calculate the number of ounces of the self-tanning lotion (), so we solve for that variable:
And substitute our values in this formula, to get:
