Answer:
Paper route earnings each week=($87.8-$37.8) / 10 =$5
If $5=20% we have to find how money is the 100%.
$5-----------------20%
x------------------100%
x=($5*100%) / 20%=$25
solution: $25.00
Step-by-step explanation:
Answer: he saved $15
Step-by-step explanation:
The regular price is $5.00 per rose bush, but last week they were on sale at 2 for $8.50. This means that the amount that one would cost is
8.5/2 = $4.25
If Jim bought 20 rose bushes last week, it means that the amount that he paid for 20 rose bushes is
20 × 4.25 = $85
The regular price is $5.00 per rose bush. If he had bought at the regular price, the amount that he would have paid is
5 × 20 = $100
Therefore, the amount saved by the bushes on sale is
100 - 85 = $15
The value of the product expression given as product of (2i) and (5+3i) is 10i -6
<h3>How to determine the product?</h3>
The product expression is given as:
product of (2i) and (5+3i)
Rewrite the expression as:
(2i) * (5+3i)
Open the brackets
(2i) * (5+3i) = 10i + 6i^2
Evaluate
(2i) * (5+3i) = 10i + 6(-1)
This gives
(2i) * (5+3i) = 10i -6
Hence, the value of the product expression given as product of (2i) and (5+3i) is 10i -6
