Kylie has lemon and watermelon in a ratio of 10:71. How many watermelon does she have if she has 20 lemons
Answers
Answer:
She will have 142 watermelons
Step-by-step explanation:
First let's put our ratio
10 : 71
Since our lemons are now 20 instead of 10 we will divide 20 by 10 to see how many time we multiplied it by.
[tex]20 \div 10[/tex]
which equals 2
To find our water melon we will multiply it by 2
[tex]71 \times 2[/tex]
which equals 142
She will have 142 watermelons

Frank is going to buy some ties
at $7.50 per tie and some shirts
at $18.50 per shirt. If he buys
twice as many ties as shirts and
spends no more than $205, what is the greatest number of shirts he
can buy? [All prices include tax.]
Answers
Answer:
6 shirts
Step-by-step explanation:
The cost of a shirt and 2 ties is ...
$18.50 +2(7.50) = $33.50
For $205, Frank can buy $205/$33.50 = 6.12 sets of shirt and ties.
Frank can buy 6 shirts (and 12 ties) for an amount less than $205.
_____
Additional comment
Frank's cost will be $201 for that purchase.

Jon paid $40 for a shirt, but later that week the
price had been raised by 15%...how much did
the shirt go up?
Please give a walk through ty
Answers
Answer:
15% of 40 is 6
9514 1404 393
Answer:
$6
Step-by-step explanation:
15% is the ratio of the price increase to the original price.
As a fraction 15% = 15/100 (fifteen hundredths).
As a decimal, 15% = 0.15 (fifteen hundredths).
__
The statement about the price increase is telling you ...
(increase)/(original) = 0.15
Multiplying by the original price, we get ...
(increase) = 0.15×(original) = 0.15 × $40 = $6.00
The price of the shirt went up $6.00.
