The given expression actually represents the amount left with Jared after making those purchases.

Jared has $32

He purchases 5 packs of trading cards at $3 each.

So amount spent = 5 × 3 = $15

The cost display book = $3

And the cost of another display book = $7

So total amount spent

= (5×3) +3 + 7

= 15 + 3 + 7

= $25

The expression

32- [(3×5)+3+7)

= 32 - 25

= $7

$7 is the amount left with Jared after he makes all these purchases.

What is the decimal multiplier to increase by 99%? need it now
krek1111 [17]

Answer:

To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2.

The first term of an AP is -7 and the ratio of the eight term to the third term is 7:1 calculate the common difference
alukav5142 [94]

Answer:

the common difference is 6.

Step-by-step explanation:

Given;

first term of an AP, a = -7

let the common difference = d

The third term is written as;

T₃ = a + 2d

The eight term is written as;

T₈ = a + 7d

The ratio of the eight term to third term = 7:1

\frac{T_8}{T_3} = \frac{7}{1} = \frac{a+ 7d}{a + 2d} \\\\7 =  \frac{a+ 7d}{a + 2d}\\\\Recall, a = -7\\\\7 =   \frac{-7+ 7d}{-7 + 2d}\\\\7(-7 + 2d) = -7+ 7d\\\\-49 + 14d = -7 + 7d\\\\14d -7d = -7 + 49\\\\7d = 42\\\\d = \frac{42}{7} \\\\d = 6

Therefore, the common difference is 6.
