In 1985, the cost of clothing for a certain familiy was $620. In 1995, 10 years later, the cost of clothing for this famility wa
Sholpan [36]

Answer:

$848

Step-by-step explanation:

Calculation for the cost of this familiy's clothing in 1991

First step is to calculate the amount that is increase per year

Increase per year= ($1000-$620)/(1995-1985)

Increase per year= 380/10

Increase per year= $38

Now let y be :38*x + $620 and let x be 6 years (1991-1985)

Second step is to calculate the cost of the clothing in 1991

y = 38*6 + 620

y=228+620

y = $848

Therefore the cost of this familiy's clothing in 1991 will be $848

I need help on 34 and 36
aleksley [76]
34. 65 = 3/4c - 7....add 7 to both sides
      65 + 7 = 3/4c...simplify
       72 = 3/4c...multiply both sides by 4/3, eliminating the 3/4 on the left
       72 * 4/3 = c
       288/3 = c
       96 = c

36. -5/2 = 3/4z + 1/2 ...subtract 1/2 from both sides
      -5/2 - 1/2 = 3/4z .... simplify
       -6/2 = 3/4z ....reduce
       -3 = 3/4z....multiply by 4/3. eliminating the 3/4 on the left
      -3 * 4/3 = z
       -12/3 = z
       -4 = z
