For each ounce of the product, let
x = ounces of moisturizing lotion used,
y = ounces of self-tanning lotion used.
The sum of the two lotions per ounce is equal to one ounce. Therefore
x + y = 1 (1)
Moisturizing lotion costs $0.70 per ounce.
Self-tanning lotion costs $22 per ounce.
Because the product costs $1.30 per ounce. Therefore
0.70x + 22y = 1.30 (2)
From (1), obtain
y = 1 - x (3)
Substitute (3) into (2).
0.70x + 22(1 - x) = 1.30
0.70x - 22x + 22 = 1.30
-21.3x = -20.7
x = 0.9718 ounces
From (3), obtain
y = 1 - 0.9718 = 0.0282 ounces.
A batch of the product is 700 ounces. Therefore the amount of self-tanning lotion used is
700*y = 700*0.0282 = 19.74 ounces
Answer: 19.74 ounces

Answer:
The acceleration will also be uniform when velocity changes by the same amount over time.
Step-by-step explanation:
Acceleration is defined as a rate of change of velocity per unit time.
Unit of the acceleration is m/
So,here when the velocity changes by the same amount over time, the change here will be <u>UNIFORM</u>.
Hence, the acceleration will also be uniform when velocity changes by the same amount over time.
