8. a family pays $19 each month for internet access. next month, the cost will increase by 5% because of an equipment fee. after this increase, what will be the cost for the internet access?

Explanation:

Step1: Convert % to decimal, multiply

$250\% = 2.5$, $2.5 \times 25 = 62.5$

Step2: Convert % to decimal, multiply

$108\% = 1.08$, $1.08 \times 50 = 54$

Step3: Convert % to decimal, multiply

$75.2\% = 0.752$, $0.752 \times 130 = 97.76$

Step4: Convert % to decimal, multiply

$0.5\% = 0.005$, $0.005 \times 60 = 0.3$

Step5: Convert % to decimal, multiply

$2.4\% = 0.024$, $0.024 \times 20 = 0.48$

Step6: Convert % to decimal, multiply

$7.5\% = 0.075$, $0.075 \times 30 = 2.25$

Step7: Convert % to decimal, multiply

$17.7\% = 0.177$, $0.177 \times 110.2 = 19.5054$

Step8: Calculate 5% increase, add to base

$5\% \times 19 = 0.05 \times 19 = 0.95$, $19 + 0.95 = 19.95$

Answer:

1. $62.5$
2. $\$54$
3. $97.76$
4. $0.3$
5. $0.48$
6. $2.25$
