Costs for the high school picnic have increased by 30% in 3 years. There is $235.00 in the school picnic fund. Three years ago, juice cost $57.25 and food cost $129.80. ls there enough money in the fund to pay this years bill?

Answer 1

#$243.14 # is needed, so there is a shortfall of #8.14# in the fund.

The costs 3 years ago were #57.25+129.80 = $187.03#

Increase that by 30% to find the cost this year.

This is the same as finding #130%#
#187.03 xx 130/100 = $243.14#

AS there is only #$235 in the fund, there is not quite enough money.

However, the shortfall is only $8.14...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [another way of increasing by 30%, is to find the 30% amount and add it on to #187.03#
#30/100 xx 187.03 = $56.11# increase this year.
#187.03+56.11 = $243.14#]

No, there is not enough money in the fund to pay this year's bill. To determine if there is enough money, we need to calculate the current cost of juice and food.

Three years ago, the cost of juice was 57.25andfoodwas57.25 and food was 129.80.

To find the current cost of juice, we need to increase it by 30% over three years: Current cost of juice = 57.25+(57.25 + (57.25 * 0.30) = $74.43

To find the current cost of food, we do the same: Current cost of food = 129.80+(129.80 + (129.80 * 0.30) = $168.74

Now, we add the current costs of juice and food to find the total cost of this year's bill: Total cost = 74.43+74.43 + 168.74 = $243.17

Since the total cost of this year's bill is 243.17,andthereisonly243.17, and there is only 235.00 in the school picnic fund, there is not enough money to pay the bill.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
