On a final exam for math, Lauren was required to answer a combination of at least 15 equations or word problems. Lauren knew that each equation would take her 5 minutes to solve and each word problem would take 8 minutes. Lauren had 120 minutes to complete the final exam. Write an inequality for each constraint. Use the
‾‾√

button above to type formulas with appropriate inequality symbols. (Hint: one constraint is time and the other is the number of needed items. Let x be the number of equations and y be the number of word problems solved.)

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
