you have savings of $100. you plan to save another $100 at the beginning of each year for 5 years. The account pays annual intrest of 8 percent, coumpounded quarterly. the ending balance (pincipal plus interest) will be $ at the end of 5 years?

$638.10

Step-by-step explanation:

= $100 (1 + 2/100)^4

= $100 (1 + 0.02)^4  

= $100* 1.0824

= $108.24

For the second year = $100+ $108.24= $208.24

= $ 208.24 * 1.0824

= $225.41

For the third year = $100 + $ 225.41 = $325.41

= $325.41 * 1.0824

= $352.23

For the fourth year = $100 + $ $352.23 = $452.23

= $452.23 * 1.0824

= $ 489.51

For the fifth year =  $100+ $489.51 = $589.51

= $589.51 * 1.0824

= $ 638.10

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
