Question

Hi uwu pls help me with math i'm bad at it :(

1) You are using the equation 4(p – 7) = 44 to determine how many pictures can be saved at one time to the photo stream on your cell phone. Describe the operations in the order that you will perform them to solve the equation.

2) How many pictures can you save at one time to the photo stream on your cell phone? Solve the equation you wrote in part a to find the unknown variable.

3) The phone case you want to buy is marked down 30%, and you have a 25% off coupon. You pay $42.00. Can this equation be used to find the original price of the phone case? If so, what is the original price of the item? Explain.
3/4(0.7c) = 42

Answer 1

i dont know

Explanation:

Answer 2

Question #1: p=18

Question #2: uwu sorry I had trouble with this one too

Question #3: $65.10

Explanation:

Question #1:

Step 1: multiply 4 by both products in the parenthesis to get 4p - 28 = 44,

Step 2: move the 28 to the other side so you have 4p = 44 + 28,

Step 3: add both products on the right to get 4p = 72,

Step 4: divide 4 on both sides so you are left with p = 72 ÷ 4,

Step 5: the equation to get the total of p = 18

Question #3:

Step 1: Simplify 30% to 0.30 (30÷100)

Step 2: multiply 0.30 by 42 to get 12.6

Step 3: Simplify 25%, (not sure how but) 10.5

Step 4: Add 42.00 + 12.6 + 10.5 = $65.10
